Celebrities react to Donald Trump's Senate impeachment trial

Outspoken celebrities took to Twitter on Tuesday to comment on the first day of the historic second Senate impeachment trial of former President Donald Trump. 

Bette Midler, Padma Lakshmi and Joy Behar were among those sharing their views.

Trump, who left office Jan. 20, faces potential consequences for his alleged role in the Jan. 6 riot at the U.S. Capitol that left several people dead and briefly interrupted the Senate from certifying the Electoral College votes, which were in favor of Joe Biden.

Democrats in Congress, and even some Republicans, were outraged that Trump had gathered a rally in Washington, D.C., that day and repeated his claims that he won the presidential election. Many lawmakers claimed Trump did not do enough to stop the attack once crowd members began breaching the Capitol about one hour after his rally's conclusion.

On Tuesday, the Senate impeachment trial began with opening statements and debate between House impeachment managers and Trump’s defense lawyers. As the events unfolded live, several of Trump’s critics in Hollywood took to social media to discuss the ongoing trial.

Many called for Senate Republicans to convict the former president on a Jan. 13 House charge of "inciting an insurrection" -- while others simply lambasted Trump over the riot. Others, however, joined the myriad of voices dunking on Trump's defense attorneys, who were criticized for a relatively lackluster performance that reportedly left the former president "beyond angry." 

Jon Stewart, who is relatively new to Twitter, was among the first to make a joke about Trump's legal team.

"I can’t believe they assigned Trump such a s----y Public Defender," he wrote. 

"These lawyers represent their client’s persona well: nonsensical and false victimized," wrote "Star Trek" actor George Takei.

In a follow-up tweet, he added: "Trump keeps logging on to Twitter to try and fire Bruce Castor."

Barbara Streisand was less snarky, instead opting to compliment House manager Jamie Raskin.

"Congressman Raskin moved me to tears describing his personal story of the seditionist January 6th insurrection," she wrote.

Longtime Trump rival Rosie O'Donnell was among the first to call for Trump's conviction, writing: "trump designed and directed his supporters to storm the capital - he is guilty AF - country over trump - come on GOP - convict him #ConvictTrump." 

"Defense by incoherence! Brilliant!" wrote Patricia Arquette.

"I just hope this impeachment trial gets to the bottom of who riled up that violent mob waving all those Trump flags. What a mystery!" mused comedian Patton Oswalt.

"We’re finally saying 'Merry Impeachment' again!" Stephen Colbert wrote.

"We've all had to reckon with the trauma of January 6th," author and TV host Padma Lakshmi wrote. "Our children have seen footage of an armed mob hoisting Trump flags, storming the Capitol while our representatives ran for their lives. A vote to convict would deter this from ever happening again. #impeachmenttrial."

"If this were a secret ballot, Trump’s conviction would be close to unanimous. For the sake of the preservation of Democracy, I urge Republican Senators to vote your conscience," longtime Trump critic Rob Reiner wrote.

"If Trump was immediately 'horrified' by the Capitol attack, WHY DID HE WAIT 2 1/2 HOURS BEFORE TELLING THEM TO LEAVE?" "Two and a Half Men" star Jon Cryer wrote in response to a tweet that Trump's lawyers described the former president as being "horrified" by the attack.

"The View" star Joy Behar called out some key Republicans by name in her rebuke.

"Not one of these insurrectionists would be at the capitol that day if Trump didn’t tell them to go. I know it, you know it, Trump knows it, Coyote head knows it and Lindsay Graham and his band of merry traitors know it. That is all," she wrote.

"Why do any #Republicans even WANT #Trump to be able to run again? Don't they want their OWN shot at getting in and f---ing up the country? Why give up all that glory? #ConvictAndDisqualifyTrump," Bette Midler added.

"If u don't think trumpy incited that riot, u musta not been watching it live that day. The entire time I just kept saying 'holy s--- they r doing it..hes tellin em, says hes goin 2 and they r actually doing it...' it was astonishing in real time. #impeachment #ImpeachmentDay," comedian Kathleen Madigan wrote.

"1.6.21 right-wing militants attacked our country, fueled by lies peddled by many GOP, desperate to overturn the will of voters. We must hold those responsible accountable so we can make this a country where our leaders reflect the very best of every kind of American. #impeachment," Alyssa Milano wrote.

"Impeachment day! I’m making my husband call me 'Miss Griffin, Esquire' today. I also told him if he wants to get some, he has to ask to approach the bench," comedian Kathy Griffin joked.

Several others tweeted throughout the day as well.

"#VoteToConvict," Rosie O'Donnell simply wrote.

"Just catching up on the #ImpeachmentTrial here," actor Jeffrey Wright tweeted. "Is this ol' boy Castor a for real attorney?"

In reference to possibly abstaining from a vote, Debra Messing added: "@SenateGOP If you'd like to honor your oath but fear retribution for voting guilty, you could come down with the flu that day. Think about it."
