作为调查针对前总统唐纳德·特朗普(Donald Trump)的暗杀企图周日加剧，美国特勤局(U.S. Secret Service)正受到审查，因为人们越来越怀疑所谓的枪手是如何从屋顶上发射一连串子弹的，而特朗普是从宾夕法尼亚州户外集会舞台的有利位置上发表讲话的。

　　美国联邦调查局确定了可疑枪手执法官员告诉ABC新闻，宾夕法尼亚州贝瑟尔公园20岁的托马斯·马修·克鲁克斯(Thomas Matthew Crooks)持有一支AR-15式步枪，在特勤局神枪手开枪打死他之前开了8枪。

　　枪击事件发生后，拜登总统在椭圆形办公室发表讲话，呼吁保持冷静和团结。

　　“虽然我们可能有分歧，但我们不是敌人，我们是邻居，我们是朋友，同事，公民，最重要的是，我们是美国同胞，”他说。“我们必须站在一起。”

　　拜登指责集会上展示的暴力，并警告说“我们不能在美国走这条路。”

　　了解调查情况的消息人士告诉美国广播公司新闻，在枪击事件发生前，当局收到了一个形迹可疑的人的报告，并很快在屋顶上发现了枪手。消息人士称，一名警官试图爬上屋顶，但遭到了枪手的威胁，几分钟后响起了枪声。尚不清楚该信息是否被传递给特勤局。

　　嫌疑人似乎穿着t恤和棕色迷彩短裤，与他所在建筑的颜色融为一体。

　　根据多名执法消息人士的说法，联邦酒精、烟草、枪支和爆炸物管理局(ATF)进行的紧急追踪发现，在暗杀企图现场发现的枪支是嫌疑人的父亲在2013年合法购买的。

　　负责匹兹堡美国联邦调查局办公室的特工凯文·罗杰克(Kevin Rojek)表示，在嫌疑人的汽车中发现了一个可疑装置，正在进行分析。根据Rojek的说法，另一个是在他家里发现的，两个都很简陋。

　　联邦调查人员说，他们没有发现嫌疑人和任何国际恐怖组织之间的联系。调查人员表示，他们仍在调查嫌疑人是否与国内恐怖组织有任何联系。消息人士称，枪击事件越来越像是独狼的行动。

　　“目前，我们掌握的信息表明，枪手是单独行动的，目前没有公共安全问题，”罗杰克周日下午在与记者的电话中说。“目前，我们还没有确定与该主题相关的意识形态，但我想提醒大家，我们仍处于这项研究的早期阶段。”

　　“攻击我们的民主”

　　美国联邦调查局主任克里斯托弗·雷(Christopher Wray)也在电话中表示，对川普的暗杀企图“无异于对民主和我们民主进程的攻击”

　　“企图暗杀总统候选人只能被描述为绝对卑鄙，在这个国家是不会被容忍的，”雷说。

　　罗杰克说，嫌疑人的枪和手机已被送往弗吉尼亚州匡提科的美国联邦调查局实验室进行分析。

　　Rojek说，嫌疑人的家人正在配合调查，并补充说，嫌疑人没有已知的精神病史。

　　除了将枪击事件作为暗杀企图进行调查外，美国联邦调查局反恐部门助理主任罗伯特·威尔斯表示，此案也作为潜在的国内恐怖主义行为进行调查。

　　罗杰克说，美国联邦调查局已经收到了2000多条关于枪击的线索。

　　根据五角大楼的说法，嫌疑人与美国军方没有关系。

　　关于所谓枪手的细节浮出水面

　　与此同时，Bethel Park技术护理和康复中心周日向ABC新闻证实，嫌疑人克鲁克斯在该机构担任饮食助理，他通过了就业背景调查。

　　“得知他的参与，我们感到震惊和难过，因为托马斯·马修·克鲁克斯毫无顾虑地履行了自己的职责，他的背景调查也是清白的。我们现在正全力配合执法人员的工作，”该中心的管理员玛茜·格林说。

　　克鲁克斯的两名前高中同学告诉美国广播公司新闻，嫌疑人被高中步枪俱乐部拒绝，并被要求不要返回。

　　“他不仅仅是没有入选球队，他被要求不要回来，因为他是一个多么糟糕的射手。这被认为是危险的，”詹姆森·迈尔斯说，他的一位老同学说。“季前赛的第一天，他基本上连靶子都打不中。”

　　官员们说，调查人员还在梳理嫌疑人的社交媒体足迹，寻找线索。

　　据执法部门消息人士称，调查人员正在调查嫌疑枪手最近似乎在消费哪些被称为错误信息的信息，以及这些信息是否在这起事件中发挥了任何作用。消息人士称，到目前为止，调查人员尚未发现与极端组织或个人的任何联系，尽管他们继续从嫌疑人的手机和其他数字设备中搜索信息。

　　简报结束后，拜登在白宫情况室发表讲话说:“我们必须团结一致，展示我们是谁。”

　　总统说，调查人员还没有确定枪击的动机，他要求美国人不要对嫌疑人的动机或从属关系做出假设。

　　拜登说:“让美国联邦调查局做他们的工作，让他们的伙伴机构做他们的工作。”。“我已经指示调查要彻底、迅速，调查人员将拥有完成调查所需的一切资源。”

　　拜登说，他“一直坚持我对特勤局的指示，为他(特朗普)提供一切必要的资源、能力和保护措施，以确保他的持续安全。”

　　他说，他还指示特勤局“审查共和党全国代表大会的所有安全措施”，该大会定于周一在密尔沃基举行。他说，他还下令对周六集会的安保工作进行独立调查。

　　拜登说，他周六晚上与特朗普进行了“短暂但良好的交谈”，并补充说，“我真诚地感谢他做得很好，正在康复。”

　　总统说，他计划周日晚上在白宫向全国发表讲话。

　　After Trump assassination attempt, questions swirl about what happened

　　As theinvestigationinto the assassination attempt on former President Donald Trump intensified Sunday, the U.S. Secret Service was coming under scrutiny as questions mounted on how the alleged gunman managed to fire a barrage of shots from a rooftop with a vantage point of the outdoor Pennsylvania rally stage Trump was speaking from.

　　The FBI identified thesuspected gunmanas 20-year-old Thomas Matthew Crooks of Bethel Park, Pennsylvania, whom officials said was armed with an AR-15-style rifle and fired up to eight shots before a Secret Service sharpshooter shot and killed him, law enforcement officials told ABC News.

　　President Biden, in an Oval Office address, urged calm and unity after the shooting.

　　"While we may disagree, we are not enemies, we’re neighbors, we’re friends, co-workers, citizens, and most importantly, we are fellow Americans," he said. "We must stand together."

　　Biden railed against the violence exhibited at the rally and warned "we must not go down this road in America."

　　Sources briefed on the investigation told ABC News that ahead of the shooting, authorities received reports of a person acting suspiciously and soon spotted the gunman on the roof. An officer tried to make it to the roof but was threatened by the shooter and moments later shots rang out, the sources said. It's unclear whether the information was passed on to Secret Service.

　　The suspect appeared to be wearing a T-shirt and tan camouflage shorts that blended into the colors of the building he was perched atop.

　　Watch the ABC News special, "Trump Assassination Attempt Minute by Minute," Sunday at 8 p.m. ET

　　The firearm recovered at the scene of the assassination attempt was legally purchased in 2013 by the suspect's father, an urgent trace conducted by the federal Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) found, according to multiple law enforcement sources.

　　Kevin Rojek, the special agent in charge of the Pittsburgh FBI office, said a suspicious device was found in the suspect's car and was being analyzed. Another was found in his home and both were rudimentary, according to Rojek.

　　Federal investigators said they have found no links between the suspect and any international terrorist group. Investigators said they're still looking into whether the suspect had any ties to domestic terrorist groups. Increasingly, the shooting is looking like the action of a lone wolf, sources said.

　　“At this time, the information that we have indicates that the shooter acted alone and that there are currently no public safety concerns,” Rojek said in a call with reporters Sunday afternoon. “At present, we have not identified an ideology associated with the subject, but I want to remind everyone that we're still very early in this investigation."

　　'Attack on our democracy'

　　Also on the call was FBI Director Christopher Wray, who said the assassination attempt on Trump "was nothing short of an attack on democracy and our democratic process."

　　"An attempt to assassinate a presidential candidate can only be described as absolutely despicable and will not be tolerated in this country,” Wray said.

　　Rojek said the suspect's gun and cellphone have been sent to the FBI laboratory in Quantico, Virginia, to be analyzed.

　　Rojek said the suspect's family is cooperating with the investigation and added that the suspect had no known history of mental illness.

　　In addition to investigating the shooting as an assassination attempt, Robert Wells, assistant director of the FBI's Counterterrorism Division, said the case is also being probed as a potential domestic terrorism act.

　　The FBI has received more than 2,000 tips on the shooting, Rojek said.

　　The suspect had no U.S. military affiliation, according to the Pentagon.

　　Details about alleged shooter emerge

　　Meanwhile, the Bethel Park Skilled Nursing and Rehabilitation Center confirmed to ABC News on Sunday that the suspect Crooks worked at the facility as a dietary aide and that he passed a background check for employment.

　　"We are shocked and saddened to learn of his involvement as Thomas Matthew Crooks performed his job without concern and his background check was clean. We are fully cooperating with law enforcement officials at this time," said Marcie Grimm, administrator of the center.

　　Two former high school classmates of Crooks told ABC News that the suspect was rejected from the high school rifle club and asked not to return.

　　"He didn't just not make the team, he was asked not to come back because how bad of a shot he was. It was considered like, dangerous,” said Jameson Myers, one of the former classmates said. "On the first day of pre-season he basically couldn't even hit the target."

　　Investigators are also combing through the suspect's social media footprint for clues, officials said.

　　Investigators are looking at what sources describe as misinformation the suspected gunman appeared to have been recently consuming and whether it played any role in the incident, according to law enforcement sources. So far, investigators have not uncovered any ties to extremist organizations or individuals, though they continue to scour information from the suspect's phone and other digital devices, the sources said.

　　Biden tells nation 'let the FBI do their job'

　　President Joe Biden and Vice President Kamala Harris were briefed on the investigation Sunday by FBI Director Christopher Wray, Attorney General Merrick Garland, Homeland Security Secretary Alejandro Mayorkas, National Security Advisor Jake Sullivan and U.S. Secret Service Director Kim Cheatle.

　　Following the briefing, Biden spoke from the White House Situation Room, saying, "We must unite as one nation to demonstrate who we are."

　　The president said investigators have not determined a motive for the shooting and he requested that Americans not make assumptions on the suspect's motives or affiliations.

　　"Let the FBI do their job and their partner agencies do their job," Biden said. "I've instructed that the investigation be thorough and swift and the investigators will have every resource they need to get this done."

　　Biden said he has "been consistent in my direction of the Secret Service to provide him [Trump] with every resource, capability and protective measure necessary to ensure his continued safety."

　　He said he has also directed the Secret Service to "review all security measures for the Republican National Convention" scheduled to begin on Monday in Milwaukee. He said he has also ordered an independent investigation of the security provided at Saturday's rally.

　　Biden said he had a "short but good conversation" with Trump late Saturday night, adding, "I'm sincerely grateful that he is doing well and recovering."

　　The president said he plans to address the nation from the White House Sunday night.

　　Gun shots rang out as Trump began his speech

　　Trump was less than 10 minutes into his campaign speech and had turned his head to look at a jumbotron when the gunfire began, according to witnesses and video of the moment. Video captured the former president reaching for his ear and going to the ground as multiple shots could be heard.

　　A man who was attending the rally was fatally shot and two other rallygoers were shot and wounded, federal officials said. Pennsylvania Gov. Josh Shapiro identified the deceased victim as Corey Comperatore, 50. The Pennsylvania State Police on Sunday identified the wounded bystanders as 57-year-old David Dutch of New Kensington, Pennsylvania; and 74-year-old James Copenhaver of Moon Township, Pennsylvania. Both are listed in stable condition, according to the state police.

　　Shapiro said Comperatore, a firefighter and the father of two daughters, died while protecting his family. Shapiro said Comperatore's wife asked him to share that "Corey dieda hero, that Corey dove on his family to protect them at this rally."

　　The FBI is leading the investigation. Overnight, investigators said they executed a warrant at Crooks' home in Bethel Park, about 53 miles south of Butler, Pennsylvania, where the shooting at the Trump rally occurred.

　　The roof where the suspect fired from had been surveyed during security preparations for the event, a law enforcement source told ABC News.

　　The roof was empty during those security preparations, the source said.

　　It remains under investigation why the Secret Service or local law enforcement didn't post someone at the building to prevent anyone from accessing the roof.

　　Suspicious activity at nearby building

　　Authorities outside the rally's security perimeter were alerted there was a man acting suspiciously, multiple sources briefed on the probe told ABC News. Local and state police, responsible for security outside that perimeter, began to search for a potential suspect and within minutes on the roof of an agriculture building about 400 feet from where Trump was speaking, the sources said.

　　Butler County Sheriff Michael T. Slupe, who was at Saturday's rally when the shooting broke out, told ABC News that he was informed by other law enforcement that Butler Township police officers were looking for a suspicious person in the area of the rally just before the shooting started.

　　Slupe said he was told that a Butler Township police officer was vaulted up to the roof where the shooter was located and that the suspect turned and aimed at the officer, who immediately retreated down to the ground and radioed in the gunman's location. Slupe said the gunman then proceeded to open fire on the rally.

　　Butler Township police did not respond to calls from comment from ABC News.

　　It is unclear as of now whether this information was passed along to the Secret Service, responsible and focused for the security of the former president and the crowed inside the security zone.

　　Secret Service denies report it rebuffed Trump team request for beefed-up security

　　The former president, who was wearing a Make America Great Again hat, was seen in a video clutching his right ear and going to the ground as several Secret Service agents rushed to cover him with their bodies and people in the crowd also ducked for cover.

　　Anthony Guglielmi, a spokesperson for the Secret Service, posted a statement on X on Sunday disputing media reports that the Secret Service rejected a request from Trump's campaign team to supply additional security resources.

　　"There's an untrue assertion that a member of the former President's team requested additional security resources& that those were rebuffed. This is absolutely false. In fact, we added protective resources& technology& capabilities as part of the increased campaign travel tempo," Guglielmi wrote.

　　Some senators call for investigation of Secret Service

　　"I call on you to launch a full, public and comprehensive committee investigation into this assassination attempt and failures to adequately protect the president," Sen. Josh Hawley, R-Mo., said in a letter released Sunday formalizing a call for the Senate Homeland Security Committee to investigate the attack on Trump.

　　The House Homeland Security Committee also asked the Secret Service director, Kimberly Cheatle, to testify soon.

　　Xochitl Hinojosa, spokesperson for the Department of Justice, said in a statement Sunday that Attorney General Merrick Garland has canceled plans to travel to Nevada, Utah and Kansas this week to meet with local law enforcement and speak at the National Bar Association. Hinojosa said Garland will stay in Washington, D.C., to closely monitor the investigation of the attempt on Trump's life.

　　"The Attorney General continues to receive regular briefings regarding the attack at former President Trump’s rally," Hinojosa said. "This morning he met with Department personnel and partners from across government."
