As the House prepares to bring the impeachment charge against Donald Trump to the Senate for trial, a growing number of Republican senators say they are opposed to the proceeding, dimming the chances that former president will be convicted on the charge that he incited a siege of the U.S. Capitol.

House Democrats will carry the sole impeachment charge of “incitement of insurrection” across the Capitol late Monday evening, a rare and ceremonial walk to the Senate by the prosecutors who will argue their case. They are hoping that strong Republican denunciations of Trump after the Jan. 6 riot will translate into a conviction and a separate vote to bar Trump from holding office again.

But instead, GOP passions appear to have cooled since the insurrection. Now that Trump's presidency is over, Republican senators who will serve as jurors in the trial are rallying to his legal defence, as they did during his first impeachment trial last year.

“I think the trial is stupid, I think it’s counterproductive,” said Sen. Marco Rubio, R-Fla. He said that "the first chance I get to vote to end this trial, I’ll do it” because he believes it would be bad for the country and further inflame partisan divisions.

Trump is the first former president to face impeachment trial, and it will test his grip on the Republican Party as well as the legacy of his tenure, which came to a close as a mob of loyal supporters heeded his rally cry by storming the Capitol and trying to overturn Joe Biden's election. The proceedings will also force Democrats, who have a full sweep of party control of the White House and Congress, to balance their promise to hold the former president accountable while also rushing to deliver on Biden's priorities.

Arguments in the Senate trial will begin the week of Feb. 8. Leaders in both parties agreed to the short delay to give Trump's team and House prosecutors time to prepare and the Senate the chance to confirm some of Biden’s Cabinet nominees. Democrats say the extra days will allow for more evidence to come out about the rioting by Trump supporters, while Republicans hope to craft a unified defence for Trump.

Sen. Chris Coons, D-Del., said in an interview with The Associated Press on Sunday that he hopes that evolving clarity on the details of what happened Jan. 6 “will make it clearer to my colleagues and the American people that we need some accountability.”

Coons questioned how his colleagues who were in the Capitol that day could see the insurrection as anything other than a “stunning violation” of tradition of peaceful transfers of power.

“It is a critical moment in American history and we have to look at it and look at it hard,” Coons said.

An early vote to dismiss the trial probably would not succeed, given that Democrats now control the Senate. Still, the mounting Republican opposition indicates that many GOP senators would eventually vote to acquit Trump. Democrats would need the support of 17 Republicans — a high bar — to convict him.
