Georgia Rep. Doug Collins, an ardent ally of President Donald Trump and vocal opponent of his impeachment, is expected to announce he will challenge fellow Republican and newly appointed Sen. Kelly Loeffler for her seat this year, a Republican official said Monday. The decision by the four-term lawmaker could complicate the GOP's chances of holding onto the seat as Republicans battle to retain their Senate majority in this November's elections. Loeffler, 49, was appointed this month to the seat by Republican Gov. Brian Kemp to replace the retired Sen. Johnny Isakson, who left office due to deteriorating health.

USA Today Washington correspondent Christal Hayes answers the internet, "What happens if the Senate votes to impeach Trump?"

This might be the most easily debunked claim of the whole impeachment trial.President Trump's team of defenders got their turn on the Senate floor on Monday, with one of them, Trump lawyer Jane Raskin, employing a new strategy to distance Trump from his lawyer and Ukraine link Rudy Giuliani altogether. "In this trial, in this moment, Mr. Giuliani is just a minor player, that shiny object designed to distract you," Raskin said. "Senators, I urge you most respectfully, do not be distracted."While Raskin may try to downplay Giuliani's involvement, the transcript of Trump's July phone call with Ukrainian President Volodymyr Zelensky, which Trump so often begs the world to read, would say otherwise. Giuliani's name comes up no less than six times in that call memo, with Trump mentioning "Giuliani" two times and "Rudy" twice as well.There are also all those times impeachment witnesses told the House that Giuliani was deeply tied to Trump's Ukraine dealings, with a few of them explicitly saying how Trump had told them to "talk to Rudy" when they had concerns about the country. Oh, and don't forget all those other times Giuliani himself talked up his involvement with Ukraine while making gaffe after gaffe on national TV.More stories from theweek.com Mike Pompeo is a disgrace If Bernie wins John Bolton's quest for vengeance and book sales

Fox News' Chris Wallace is once again calling out pro-Trump spin on the network, even slamming one contributor on air in a tense exchange.Wallace spoke Monday about the explosive New York Times report that former National Security Adviser John Bolton in his upcoming book writes that President Trump told him he wanted to continue withholding aid to Ukraine until officials helped with investigations into former Vice President Joe Biden and his son.To get a sense of how "big" this news is, one only has to look at Trump supporters "spinning like crazy that it isn't big news," said Wallace. This only reinforces that this is a "really important development in this case," he continued, per Mediaite.Wallace went on to observe that it's now "much, much less likely" that Trump's impeachment trial will wrap up on Friday without any witnesses being called, as the Bolton news makes it "awfully hard" for Republican senators on the fence about calling witnesses to vote against doing so.> Fox News' Chris Wallace on the Bolton news: "If you want a sense of how big the news is that we've heard in the past 12-14 hours, listen to the Trump supporters...spinning like crazy that it isn't big news and you get a sense that this is really an important development." pic.twitter.com/o5xl6xj09e> > -- Justin Baragona (@justinbaragona) January 27, 2020Not long after, Wallace got into an argument with contributor Katie Pavlich about the idea of calling Bolton to testify after she claimed that in "every impeachment beforehand, the witnesses that were called had been called in the House before being brought to the Senate.""In the Clinton impeachment, they'd been called by the independent counsel," Wallace told her, adding, "Get your facts straight!" > Whoa, sparks fly on Fox News: Chris Wallace tells @KatiePavlich, "Get your facts straight!" @BretBaier then says, "Let's tone it down." pic.twitter.com/7IyBch5q6K> > -- Oliver Darcy (@oliverdarcy) January 27, 2020More stories from theweek.com Mike Pompeo is a disgrace All the president's turncoats Report: GOP Sen.
