Donald Trump's campaign has had a tough month. That's bad news for him but a welcome opportunity for comedian Seth Meyers, who has made a weekly ritual of skewering the presumptive GOP presidential nominee. 

On NBC's "Late Night With Seth Meyers" Monday, Meyers used his "Closer Look" segment to mock Republican leaders who have been going to great lengths to avoid talking about Trump. As the candidate's poll numbers continue alongside his offensive comments, GOP leaders who had pledged to support their party's nominee are in a bind. 

Meyers played clips of multiple congressional Republicans who dodged questions about their support of their presumptive nominee this week. Some Republicans, including Pennsylvania Sen. Pat Toomey and North Carolina Sen. Richard Burr, who are both up for re-election this year, resorted to fleeing into elevators to avoid reporters' questions. 

"I guess it is only appropriate that a campaign that began on an escalator would end huddled in an elevator," Meyers joked, referencing Trump's entrance to his campaign announcement speech at Trump Tower in New York a year ago.

The comedian also took a look at some of the strategies Republicans are using to save their party from the damage Trump's campaign could cause. Former President George W. Bush, the last Republican to hold the office, will reportedly come out of retirement to campaign for GOP senators who may be in jeopardy with Trump at the top of the ticket. 

"They are bringing in George W. Bush to clean up Trump's mess," Meyers said. "That's like calling in Justin Bieber to cover a Pitbull song."

Republicans also could try a more extreme strategy. Some campaign insiders have suggested that Trump would be willing to drop out of the race for a high enough sum. Meyers played a clip of Trump at a campaign speech Monday responding to rumors of an $150 million offer — Trump said there was no chance he would take it, but said he might consider the deal for $5 billion. 

“Okay, let me see if I got this straight: It’s a hard no for $150 million, but he will think about it for $5 billion,” Meyers said. “Based on everything I read in ‘The Art of the Deal,’ I’m thinking we could put this thing to bed for $2.2 billion, $2.3 billion, and — I’m being serious — I think we could get Mexico to pay for that.”

On Monday, Trump fired controversial campaign manager Corey Lewandowski. He currently trails presumptive Democratic nominee Hillary Clinton in recent general election polling by close to 10 points.
