Donald Trump's inauguration was on Monday and late-night hosts used it as ammo.Jon Stewart, Seth Meyers, and Jimmy Kimmel all also criticized the Democrats in their monologues.Stewart said Michelle Obama, who didn't attend, was the only Democrat with a "consistent ethical stance."As expected, late-night hosts took aim at President Donald Trump following his inauguration on Monday.It provided them with plenty to joke about, from Melania Trump's hat to the billionaire CEOs who were given front-row seats.But they also piled scorn on Democrats who were part of the proceedings, labelling many of them hypocrites in light of their dire warnings about Trump during the election campaign.John Stewart said on Monday night's "The Daily Show": "Also attending were all those people who warned Americans to shun this wannabe fascist dictator called Trump."He said: "'Look at me, Ma! Oh, let's go see Hitler and get a quick selfie first! Hello! Look at us! A quick one for the 'gram!' Former President Obama was there. George Bush seemed kind of there. Even Mike Pence showed up, I guess to let the crowd finish the job."Stewart also noted that Michelle Obama didn't attend with her husband: "Only Michelle Obama seemed to have the consistent ethical stance of saying, 'When they go low, I stay the fuck home.'"In a statement on Monday, she didn't address the inauguration but instead spoke about MLK Day.Jimmy Kimmel, who described Trump's address as "ominous," said: "Overall unlike the last time there was a lot of respect paid to tradition. Kamala Harris invited JD Vance to the Vice President's residence at the Naval Observatory for a ceremonial humping of the Millard Filmore futon."He also joked that Karen Pence didn't attend because she "opted not to celebrate the man who was all good with a bunch of yahoos killing her husband."Meanwhile, Seth Meyers said: "It was even weirder to see Democrats who correctly called Trump an existential threat to democracy, palling around with him," referring to Joe Biden having tea with Trump before sharing a limo with him to the Capitol.This is in contrast to the somber tone taken by late-night hosts in the days after Trump won the 2016 election, and Kate McKinnon dressed as Hilary Clinton to sing Leonard Cohen's "Hallelujah" in an uncharacteristically mournful moment for "Saturday Night Live."
