Alec Baldwin reprises Trump impersonation at anti-inauguration rally

Protesters have gathered around the U.S. Thursday night, in the lead-up to Donald Trump's inauguration.

New York City's rally featured the likes of Michael Moore, Mark Ruffalo, Robert De Niro, Al Sharpton and Alec Baldwin were in attendance. The latter of which just couldn't help himself.

Baldwin, who's cut a reputation for his impersonations of the president-elect on Saturday Night Live, reprised his role in front of protestors outside Trump Tower in Manhattan.

"I just want to say, I've been standing out here in the freezing cold for a long time," Baldwin said, in the voice of Trump.

"I have to go to the bathroom. I have to pee. But I'm holding it in, I'm holding it in, I'm not gonna pee. I'm going to a function at the Russian consulate tonight, I'm gonna hold it in 'till I get there.

"And then when I get to the Russian consulate, I'm going to have really, really long pee. Like the biggest pee I've ever had in my lifetime."

Following the joke, Baldwin used the rest of his speaking time to rouse the crowd in not "laying down" when the Trump administration enters power, encouraging citizens to join the IDNYC identification card program before telling the crowd what to tell their children what's happening.

"They're never too young for you to teach them about what's going on here. They're never too young for you to teach them what a real American is," he said.

"And an American wants full participation and transparency of their government."
