Even so, Democrats seeking his conviction on one count of "incitement of insurrection" face an uphill climb.
The House impeached Trump on one charge of incitement of insurrection after he encouraged supporters who went on to riot at the U.S. Capitol on January 6 in an effort to stop the counting of Electoral College votes for Biden. Five people died in the chaos. The Senate could vote to bar Trump from holding federal office if he were convicted, which is a goal Democrats support. But it could clear the way for a vote to prevent him from holding public office in the future.
Trump is facing an unprecedented second impeachment trial over the deadly storming of the Capitol building on January 6.
Following the riot on Capitol Hill, stunned Republicans struggled over how to respond to Trump's role and his failure to try to quell the violence as it was unfolding.
Senate Majority leader Chuck Schumer told MSNBC on Saturday that the trial will "show the American people - vividly, on film - what happened there in the Capitol, what Trump said".
The money dispute added to the legal team's growing frustrations over disagreements about defense strategy.
According to republicans and Trump aides, the trial, set to begin the week of February 8th, will present a simple defense: that the trial itself is unconstitutional since he's no longer in office. Trump pardoned Stone in December.
In 2005, Castor decided not to prosecute disgraced actor and comedian Bill Cosby for the sexual assault of Andrea Constand. In 2017, he sued Cosby's accuser in the case for defamation, claiming she destroyed his political career in retaliation. Chuck Schumer, Senator Schumer promised a fair and full trial.
Trump labelled that episode a Democratic "witch hunt".
And while the circumstances were far different from this second impeachment, they share the same underlying accusations that Trump was resorting to extreme and impeachable actions to win re-election in 2020.
Trump's new attorneys would appear to be the kind of lawyers who will do for his impeachment trial what Dr. Scott Atlas did for his COVID response.
Democrats, who now hold a razor-thin majority in the Senate, will have more say over how this trial will be conducted. House Republicans are expected to address the issue when they meet as a group on Wednesday. Lindsey Graham, who helped Trump secure Bowers told Axios. And it was not entirely unlikely that Trump just would not bother to put up a case at all, allowing McConnell and his other henchmen in the Senate to make his argument for him and call it a day.
