Elizabeth Warren speaks of Trump presidency in 'dog years' in 'Late Show' interview 'They were dog years. Now they're Trump years,' Warren said.

 -- Sen. Elizabeth Warren, D-Mass.,, compared President Donald Trump’s presidency to “dog years” in an interview on "The Late Show" on Monday.

The comment came after the show’s host, Stephen Colbert, pointed out that she hadn’t been on the show since the start of Trump’s presidency.

“Oh, I remember those days,” Warren said with a smile. “How long has he been president now?”

“Forty-five years ... if my bone density is any indication,” Colbert replied.

“That’s right. They were dog years, now they’re Trump years. It’s going to be hard,” she joked.

Warren hit back at Trump for referring to her as “Pocahontas” in a tweet earlier this month.

“Donald Trump thinks if he's going to start every one of these tweets to me with some kind of racist slur here, that he’s going to shut me up,” she said. “It didn’t work in the past. It’s not going to work in the future.”
