亨特·拜登的检察官联邦枪支案周三传唤了他的两名前任出庭作证，试图反驳辩方的论点，即总统的儿子在2018年填写表格购买枪支时没有吸毒。

　　总统乔·拜登的孙正义面临三项指控，即在2018年10月购买枪支时在联邦表格上撒谎。他否认有不当行为。

　　前女友佐伊·凯斯坦说，她看到他在那年9月下旬吸食快克可卡因，就在他走进特拉华州一家枪支店并从戈登·克利夫兰购买柯尔特眼镜蛇的几周前，另一名证人于周三作证。

　　亨特·拜登的前妻凯瑟琳·布勒说，亨特·拜登在吸食快克时很“生气”和“脾气暴躁”，但仍设法像瘾君子一样正常“运作”——这可能削弱了辩方关于“不存在高功能快克瘾君子”的说法

　　在法庭结束之前，检察官表示，在听取了另外六名证人的证词后，他们最早可以在周四下午休庭。

　　以下是试验第三天的四大收获。

　　前女友作证亨特·拜登吸毒

　　佐伊·凯斯坦是在一家纽约绅士俱乐部的私人舞蹈演员那里认识亨特·拜登的。她说，她在2017年12月他们相遇的那个晚上看到拜登抽烟，并且在他们长达一年的浪漫关系中一直如此。

　　在他们交往的第一周，当时24岁的凯斯坦说，她与48岁的拜登“有一种联系”——尽管他“每隔20分钟左右”使用快克。

　　凯斯坦在证词中两次表示，她没有注意到他在吸毒期间的行为变化，这让她对辩护律师阿贝·洛厄尔的说法产生了怀疑。阿贝·洛厄尔声称，他身边的人应该知道他在购买枪支时是否滥用药物。

　　凯斯坦说:“我记得当时心里想，我没有注意到他行为的变化。

　　“前十分钟他非常迷人、有魅力、友好，”她说。“抽完烟后，他还是那个迷人的人。“

　　凯斯坦还作证说，她看到他直到2018年9月20日还在马里布吸食快克——这一时间线可能会削弱辩方的论点，即他在10月12日购买枪支时滥用酒精而不是毒品。

　　但凯斯坦也在交叉询问中承认，她“不知道”从9月23日亨特·拜登离开加州到11月两人重新联系上时的情况。

　　“那么你不知道从他离开加州到你11月再次见到他的时候他在做什么?”洛厄尔问道。

　　“不知道，”凯斯坦说。

　　职员说他看着亨特·拜登填写表格

　　卖给亨特·拜登涉事枪支的枪支商店员工戈登·克里夫兰作证说，他在“大约两英尺”外看着亨特·拜登填写表格，询问申请人是否是活跃的吸毒者。

　　拜登选定购买柯尔特眼镜蛇后，克利夫兰说他要求他填写“每次购买枪支”所需的表格-4473表格。克利夫兰说，他指示拜登填写个人信息并回答以下问题，“并慢慢回答这些问题”，他作证说。

　　克里夫兰作证说，他看着亨特·拜登回答了几个问题，然后开始回答与毒品有关的问题，然后在方框中打了个“x”

　　克里夫兰说，亨特·拜登没有对这个问题表示任何困惑。

　　前妻作证说她看到了毒品残留物

　　亨特·拜登的前妻凯瑟琳·布勒作证说亨特·拜登在他们25年的婚姻中酗酒和吸毒，描述了随着丈夫吸毒的增加他们的关系如何恶化。

　　布勒作证说，当亨特·拜登精神崩溃时，“他已经不是他自己了。”

　　“他很生气，脾气暴躁，表现出他清醒时不会有的行为方式，”她说。

　　布勒说，她会发现“小包里的毒品残留物”和“破裂的烟斗”等吸毒用具——她经常会在允许女儿们使用他的车之前搜查他的车。

　　布勒在交叉询问中承认她从未亲眼见过亨特·拜登吸毒。

　　政府最早可能在周四休息

　　检察官德里克·海因斯在庭审结束前表示，他预计最快将于周四结束前结束诉讼。

　　他说，政府还有六名简要证人——包括几名执法官员和博·拜登的遗孀海莉·拜登。

　　洛威尔说，如果政府周四停止诉讼，他将准备在周五上午传唤他的第一位证人。

　　戈登·克利夫兰定于周四上午重新出庭作证。

　　4 big takeaways from Day 3 of Hunter Biden's federal gun case

　　Prosecutors in Hunter Biden'sfederal gun casesummoned two of his exes to the stand Wednesday in an effort to chip away at the defense's argument that the president's son wasn't addicted to drugs when he filled out a form to purchase a firearm in 2018.

　　PresidentJoe Biden'sson faces three counts of lying on a federal form about his drug use to procure the firearm in October of 2018. He has denied wrongdoing.

　　Ex-girlfriend Zoe Kestan said she observed him smoking crack cocaine in late September of that year, just weeks before he walked into a Delaware gun shop and purchased a Colt Cobra from Gordon Cleveland, another witness who testified on Wednesday.

　　Kathleen Buhle, the ex-wife of Hunter Biden, said Hunter Biden was "angry" and "short-tempered" when he was on crack, but nonetheless managed to "function" normally as an addict -- possibly undermining the defense's claim that "there is no such thing as a high-functioning crack addict."

　　Before court concluded, prosecutors suggested they could rest their case as soon as Thursday afternoon after hearing testimony from six additional witnesses.

　　Here are four big takeaways from Day 3 of the trial.

　　Ex-girlfriend testifies about Hunter Biden's drug use

　　Zoe Kestan, who met Hunter Biden as a private dancer at a New York gentlemen's club, said she saw Biden smoke crack the night they met in December 2017 and consistently throughout their yearlong romantic relationship.

　　In the first week of their relationship, Kestan, who was 24 years old at the time, said she "felt a connection" with the 48-year-old Biden -- despite his use of crack "every 20 minutes or so."

　　Twice during her testimony Kestan said she did not notice changes in his behavior while he was on drugs, casting doubt on defense attorney Abbe Lowell's claim that those close to him would have known whether or not he was abusing drugs at the time of his gun purchase.

　　"I remember thinking to myself that I didn't notice a change in his behavior," Kestan said.

　　"The first ten minutes he was incredibly charming and charismatic and friendly," she said. "After he had smoked, he was the same charming person."

　　Kestan also testified that she saw him smoking crack in Malibu as late as Sept. 20, 2018 -- a timeline that could undercut the defense's argument that he was abusing alcohol and not drugs when he purchased the gun on Oct. 12.

　　But Kestan also conceded on cross-examination that she had "no idea" what Hunter Biden was up to from Sept. 23, when he left California, until November, when the two reconnected.

　　"So you don't have any idea of what he was doing from the moment he left California to the moment you saw him again in November?" Lowell asked.

　　"No idea," Kestan said.

　　Clerk says he watched Hunter Biden fill out form

　　Gordon Cleveland, the gun store employee who sold Hunter Biden the gun in question, testified that he watched from "about two feet" away as Hunter Biden filled out the form that asked applicants whether they were active drug users.

　　After Biden selected the Colt Cobra for purchase, Cleveland said he asked him to fill out the form required for "every gun purchase" -- Form 4473. Cleveland said he instructed Biden to write in his personal information and answer the questions below, "and to take your time answering them," he testified.

　　Cleveland testified that he watched as Hunter Biden answered several questions before he approached the drug-related question then marked the box with an "X."

　　Cleveland said Hunter Biden did not express any confusion regarding the question.

　　Ex-wife testifies she saw drug remnants

　　Hunter Biden's ex-wife Kathleen Buhle testified about Hunter Biden's alcohol and drug abuse during their 25-year marriage, describing how their relationship deteriorated as her husband's drug abuse increased.

　　When Hunter Biden was on crack, Buhle testified, "He was not himself."

　　"He was angry, short-tempered, acting in ways he wouldn't when he was sober," she said.

　　Buhle said she would find drug "remnants in little bags" and drug paraphernalia like "a broken crack pipe" -- often enough that she would search his car before allowing her daughters to use it.

　　Buhle admitted during cross-examination that she never personally saw Hunter Biden use drugs.

　　Government could rest as soon as Thursday

　　Prosecutor Derek Hines said before court concluded for the day that he anticipated resting his case as soon as the end of the day Thursday.

　　He said the government has six brief witnesses remaining -- including several law enforcement officials and Hallie Biden, the widow of Beau Biden.

　　Lowell said he would be prepared to call his first witness on Friday morning if the government rests its case Thursday.

　　Gordon Cleveland is scheduled to return to the stand on Thursday morning when testimony resumes.
