Former New York Congressman Anthony Weiner knows a thing or two about scandal—and getting caught up in a movement.

"I cried when Hillary Clinton lost to Barack Obama," Anthony Weiner told Stephen Colbert, host of "The Late Show," on Monday night. 

"I was like that last guy," the former congressman admitted. "Like that Chinese guy in front of the tank. I was the last person to endorse Obama. But now you've seen eight years of remarkable growth. To hear Donald Trump talk, you'd think we live in a lousy country. And it's because of you and the mainstream media that give him so much oxygen."

"Really? I'm mainstream media? Thank you, I'll take that as a compliment!" Colbert exclaimed. 

Having gotten caught up in his own scandal around election time, Weiner proved an irresistible target for Colbert to ask the looming question: "What do you make of the DNC WikiLeaks email leak that just came out—as someone who is probably not a big fan of revelations through electronic media?"

Weiner is against the hack. 

"I don't like this trend of criminals hacking into Sony or hacking into the DNC leaking selective things and then we just treat it as if it's regular news and we go about talking about it. Look, if someone hacked into your emails, they could probably find most things very embarrassing that you say," Weiner pointed out. 

"Sure, sure. I'm a poor speller," mused Colbert. 

But Weiner was incorrigible. 

"The DNC is irrelevant," Weiner remarked. "The DNC doesn't have any real authority over anything. Hillary Clinton dominated the election. She won by over 4 million votes." 

Plus, Weiner pointed out, the Bernie-or-bust crowd is losing options: "They want national health care; Hillary wants that. They want a $15 minimum wage; Hillary wants that. What are they going to do, vote for Donald Trump?"

Spoiler: Trump donated to many Democratic politicians before announcing his run for president, Anthony Weiner included. Looks like another failed investment.
