"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."

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