如果唐纳德·特朗普总统的私人律师鲁迪·朱利安尼被传唤在参议院弹劾审判中作证，他准备这样做，只要他得到白宫的批准。
民主党人希望在审判中传唤更多的证人，但共和党领导人认为这可能不必要地延长审判时间，并推动最终判决。根据审判规则，传唤证人需要参议院多数票，所以四名共和党人必须与共和党领导层决裂，加入民主党。
朱利安尼告诉哥伦比亚广播公司记者凯瑟琳·赫里吉，可以传唤的证人名单中包括他。当被问及为何不参与特朗普的弹劾辩护时，这位前纽约市长解释说，他是团队成员，但不能“参与国会正在进行的事情”，因为他可能是证人。
特朗普受审的核心是指控他使用扣留的军事援助和白宫访问来迫使乌克兰总统宣布对前副总统乔拜登和他的儿子亨特进行调查，以试图影响2020年的选举。特朗普否认了这一指控，称他作为总统有义务调查腐败。
2016年11月20日，当选总统唐纳德·特朗普在新泽西州贝德明斯特的特朗普国家高尔夫俱乐部会见前纽约市长鲁迪·朱利安尼。在接受哥伦比亚广播公司采访时，朱利安尼说，如果白宫批准，他将在特朗普的参议院审判中作证。
这位前市长称，负责调查腐败的是朱利安尼，他声称已经收集了不利于民主党的确凿证据。他告诉纽约，尽管他拒绝接受众议院的文件传票，但他已经准备好与参议员分享他对乌克兰丑闻的了解每日新闻民主党不想让他作证，因为他们“知道他们在隐瞒什么”
朱利安尼说:“他们已经用各种可能的方式表明他们害怕我的出现。”每日新闻记者克里斯·索末菲在短信中说。
被起诉的前朱利安尼合伙人列夫·帕纳斯告诉MSNBC的雷切尔·玛多，朱利安尼告诉乌克兰官员帕纳斯是特朗普的代表。帕纳斯说，他是代表特朗普和朱利安尼行事的，当时他告诉乌克兰官员，“所有援助”都将在没有调查的情况下被切断。
在接受福克斯新闻的劳拉·英格拉姆采访时，朱利安尼说他被帕纳斯“误导”，他声称帕纳斯做了“许多”虚假陈述
民主党人利用证词和文件来证明这位前市长参与了可疑的外交政策交易，但朱利安尼告诉赫里吉，特朗普“从未”就他与乌克兰的交易与他讨论过军事援助。
据报道，有一个人确实进行了那次谈话，他是前国家安全顾问约翰·博尔顿。根据博尔顿的新书手稿，他声称特朗普告诉他，在乌克兰调查包括拜登在内的民主党人之前，不会公布对乌克兰的军事援助纽约时报。
特朗普否认与博尔顿有过这样的对话，朱利安尼告诉赫里吉，这位前国家安全顾问关于总统的说法“几乎令人难以置信”
民主党抓住了报道中要求博尔顿在特朗普弹劾案中作证的说法，一些共和党参议员表示他们可能会支持这一要求。朱利安尼和共和党领导层一起反对博尔顿的证词。
朱利安尼告诉赫里吉:“如果总统认为这是行政特权材料，约翰·博尔顿就不应该作证。”。
RUDY GIULIANI SAYS HE MAY BE A WITNESS IN DONALD TRUMP'S IMPEACHMENT TRIAL, WILL TESTIFY WITH WHITE HOUSE APPROVAL
If President Donald Trump's personal attorney Rudy Giuliani is called to testify in the Senate impeachment trial, he's prepared to do so, as long as he has the White House's blessing.
Democrats have wanted to call additional witnesses in the trial, but GOP leaders have argued it could unnecessarily extend the trial's length and pushed for a final judgment. According to the trial's rules, subpoenaing witnesses requires a majority Senate vote, so four Republicans would have to break ranks with the GOP leadership and join the Democrats.
Giuliani told CBS News correspondent Catherine Herridge the list of witnesses that could be called includes him. Asked why he wasn't part of Trump's impeachment defense, the former New York City mayor explained that he is on the team but can't "participate in what goes on in the Congress" because he's a possible witness.
At the center of Trump's trial is the accusation that he used withheld military aid and a White House visit to pressure Ukraine's president to announce an investigation into former Vice President Joe Biden and his son Hunter in an effort to influence the 2020 election. Trump has rejected the charge, saying he had an obligation as president to investigate corruption.
President-elect Donald Trump meets with former New York City Mayor Rudy Giuliani at the Trump National Golf Club in Bedminster, New Jersey, on November 20, 2016. During an interview with CBS, Giuliani said he would testify in Trump's Senate trial if the White House approved.
Tasked with investigating that corruption was Giuliani, according to the ex-mayor, who claims he has collected damning evidence against Democrats. While he says he's ready to share his knowledge about the Ukraine scandal with senators, despite defying a House subpoena for documents, he told the New York Daily News the Democrats don't want him to testify because they "know what they are covering up."
"They have indicated in every way possible they are afraid of my physical presence," Giuliani told Daily News reporter Chris Sommerfeldt in a text message.
Lev Parnas, an indicted former Giuliani associate, told MSNBC's Rachel Maddow that Giuliani told Ukrainian officials Parnas was Trump's representative. Parnas said he was acting on behalf of Trump and Giuliani when he told Ukrainian officials "all aid" would be cut off without an investigation.
During an interview with Fox News' Laura Ingraham, Giuliani said he was "misled" by Parnas, who he claimed made "many" "misrepresentations."
Democrats have used testimony and documents to build a case that the former mayor was involved in shady foreign policy dealings, but Giuliani told Herridge that Trump "never ever" discussed military aid with him in regard to his dealings with Ukraine.
One person who reportedly did have that conversation was former national security adviser John Bolton. In a manuscript for his new book, Bolton claimed Trump told him military aid to Ukraine would not be released until the country investigated Democrats, including Biden, according to The New York Times.
Trump denied he ever had this conversation with Bolton, and Giuliani told Herridge the former national security adviser's claims about the president were "pretty close to incredible."
Democrats seized on the reported claims to push for Bolton to testify in Trump's impeachment trial, a request some Republican senators said they might support. Giuliani joined the GOP leadership in arguing against Bolton's testimony.
"John Bolton should not testify if the president feels it's executive privilege material," Giuliani told Herridge.
