House Democrats released hundreds of pages of transcribed impeachment depositions Tuesday, including testimony from Gordon Sondland, the U.S. ambassador to the European Union and a key player in President Trump's Ukraine policy. Sondland, who testified two weeks ago that he did not recall U.S. military aid for Ukraine being conditioned on Kyiv opening investigations on former Vice President Joe Biden and his son Hunter, changed his testimony in a "supplemental declaration" submitted Monday.

Sondland declared Monday that he did in fact tell a top aide to Ukrainian President Volodymyr Zelensky that "resumption of U.S. aid would likely not occur until Ukraine provided the public anticorruption statement that we had been discussing for many weeks." He said Trump had not directly told him to offer this quid pro quo, but there was no other "credible explanation for the suspension" of the military aid. Five other administration officials have described a similar no-cash-unless-investigation scheme in their testimony.

Sen. Lindsey Graham (R-S.C.), the chairman of the Senate Judiciary Committee, told reporters on Tuesday that he isn't going to read any of the transcripts being released by House impeachment investigators, including Sondland's. "I've written the whole process off," he told CBS News. "I think this is a bunch of B.S." That's too bad, because Graham had some questions that Sondland's testimony might answer.

Graham also told Axios' Jonathan Swan in October that "if you could show me that, you know, Trump actually was engaging in a quid pro quo, outside the phone call, that would be very disturbing." And Graham isn't the only Trump supporter who would be disturbed if he read the revised testimony from Sondland, a Trump donor seen as more loyal to the president than the career diplomats and national security officials whose testimony he is now corroborating.

Former New York City Mayor Rudy Giuliani claims he'd "love" to be a witness in President Trump's Senate impeachment trial, reports The Hill.

Giuliani, who serves as Trump's personal lawyer, told radio talk show host John Catsimatidis: "I would love to see a trial. I'd love to be a witness — because I'm a potential witness in the trial — and explain to everyone the corruption that I found in Ukraine, that far out-surpasses any that I've ever seen before, involving Joe Biden and a lot of other Democrats."

Giuliani was allegedly involved in a push to pressure Ukraine into launching investigations into Trump's political rivals, working to dig up dirt on former Vice President Joe Biden and pushing out former Ukrainian Ambassador Marie Yovanovitch, who was reportedly viewed as an obstacle in obtaining the promise of investigations.

Democrats in Congress have called for the Senate impeachment trial, set to begin arguments this week, to include additional witnesses beyond those who testified in the House inquiry. Senate Republicans have so far declined the requests. No evidence has emerged to prove any wrongdoing by Democrats in Ukraine, but Giuliani said "I have those facts. I have those witnesses. I have documents, and I have recordings. And I would love to get them out in public." Summer Meza

House Intelligence Committee Chair Adam Schiff (D-Calif.) on Sunday accused the National Security Agency of withholding key documents from Congress related to Ukraine that could be relevant in President Trump's impeachment trial.

Speaking to ABC News, Schiff said the NSA appears "to be succumbing to pressure from the administration," also saying "there are signs that the CIA may be on the same tragic course." Schiff said the documents could be important to the central allegation of Trump's impeachment: that he abused his power by withholding Ukraine military aid to push the country into announcing investigations of his political rivals.

The NSA and CIA have not commented on Schiff's allegations, reports NBC News.

Fox News' Chris Wallace pointed out Sen. Lindsey Graham's (R-S.C.) updated view on witnesses in a Senate impeachment trial, but Graham swore the situation is now different.

House Democrats say "evidence overwhelmingly establishes" Trump's guilt ahead of his Senate impeachment trial, set to begin arguments on Tuesday. But they want to call new witnesses to testify, including former National Security Adviser John Bolton and Lev Parnas, an associate of Rudy Giuliani. Senate Republicans have so far denied the request.

Wallace said Graham's view that new witnesses should not appear "directly contradicts what you said as a Republican House impeachment manager in 1999 during the Clinton impeachment trial." At the time, Graham said "there may be some conflict that has to be resolved by presenting live witnesses. That's what happens every day in court and I think the Senate can stand that."

"Why were witnesses okay then, but they're over the line now?" asked Wallace.

Graham blamed the "railroad job" in the House, saying witnesses were available before the House voted to impeach Trump. "If they were that important, why didn't you call them in the House? Do you need them to make your case?" The Hill reports that in some cases, witnesses were not available or willing to testify until very recently. The White House also blocked several administration officials from appearing before the House. Summer Meza

House Democrats filed a 111-page legal brief ahead of President Trump's impeachment trial, arguing he threatens national security.

The House prosecutors laid out the argument against Trump that led to his impeachment last month on charges of abuse of power and obstruction of Congress. The legal brief says "evidence overwhelmingly establishes" Trump's guilt and says the Senate "must eliminate the threat" he poses.

The White House defense team, meanwhile, has not filed its official brief, but rejected the impeachment managers' arguments as "highly partisan." Without directly addressing allegations Trump abused his power by withholding Ukrainian aid to push for a politically-motivated investigation of his rivals, the White House castigated the "lawless process" that led to his impeachment.

Hong Kong protesters were hit with tear gas and pepper spray after demonstrators allegedly attacked a plainclothes police officer during a mass protest, reports The Washington Post.

Demonstrations have been ongoing for months, and have recently erupted in occasional violence as pro-democracy residents continue to protest the local government. Several protesters were arrested on Sunday after tens of thousands participated in a rally in Hong Kong's central district, the largest demonstration since New Year's Day when over a million people gathered.

A plainclothes officer reportedly refused to show a rally organizer his identification card, which led to an altercation. At least three people were injured. Read more at The Washington Post. Summer Meza

Former Vice President Joe Biden on Saturday claimed Sen. Bernie Sanders' (I-Vt.) campaign had released a "doctored" video that appeared to show Biden agreeing with Republican proposals regarding Social Security.

"It's simply a lie, that video is a lie," Biden told supporters of his presidential campaign in Iowa, per NBC News. He said "Bernie's people" had circulated the video, and he's "looking for his campaign to come forward and disown it, but they haven't done it yet." Politico reported the video "was not doctored by Sanders."

The video showed Biden agreeing with former House Speaker Paul Ryan's proposal to privatize Social Security, but Biden's campaign said he called the plan "correct" sarcastically, reports Bloomberg.

Sanders' campaign said Biden should "stop dodging questions about his record" and pointed to Biden's numerous other comments on the program. Read more at NBC News and Bloomberg. Summer Meza
