Stephen Colbert reviews President Trump's first week: 'He really got a lot of stuff undone'

CBS's "Late Show" returned from hiatus on Monday for its first show after Donald Trump's inauguration and host Stephen Colbert felt overwhelmed by what the new president has been up to while he was away.

"You ever regret going on vacation?" the host asked as he pondered how much Trump could do in the week he was away. "The line moves really fast on this ride. Every day, you just get back on the roller coaster and start throwing up. We've got the fast pass."

 He then joked about Trump's many planned repeals.

"You've got to give the guy credit, he really got a lot of stuff undone," Colbert said. "From Obamacare to climate change to torture, he's already moved the country back to 2004. If this keeps up, pretty soon I'm going to launch 'The Colbert Report.'"

Colbert didn't waste any time getting to the most current controversy of the new Trump administration: the immigration ban. In an executive order on Friday, Trump temporarily blocked travelers from entering the US from seven predominately Muslim countries and banned all refugees from entering for the next 120 days.

"There are currently more refugees around the world than at any time since World War II," Colbert said. "The poem on the Statue of Liberty now reads, 'Don't let it hit ya where the good Lord split ya.'"

Like fellow late-night host Seth Meyers on Monday, Colbert expressed his awe of the tens of thousands of protesters who filled airports and US landmarks across the country.

"Do you have any idea how angry how people have to be to voluntarily go to JFK?" he said the New York City airport.
