Massachusetts Sen. Elizabeth Warren excoriated Donald Trump for his Thursday night acceptance speech for the Republican nomination, while blasting the GOP's four-day gathering as "the nastiest, most divisive convention that we've seen in half a century."

The Democratic senator, appearing on CBS' "The Late Show with Stephen Colbert," suggested that Bernie Sanders supporters would defy Trump's call to join them to defeat a rigged system.


"What Donald Trump says is there’s a problem out there and what you have to understand is that it's all about each other," Warren said. "What you need to be afraid of is every other American. I've got to tell you, that speech tonight, he sounded like some two-bit dictator of some country that you couldn't find on a map."

Colbert responded, "I want to defend him a second, he's not a two-bit dictator, he sounded like a billionaire dictator. Two bits is insulting to the man."

"He sounded like a dictator of a small country rather than a man who is running for the highest office of the strongest democracy on the face of this Earth. That's what he sounded like," Warren remarked.

Previewing next week's Democratic convention, Warren said speakers "will talk about how we're stronger together."

"What Donald Trump says is turn on each other. And the consequence of that one is when you turn on each other is the same guys in power, the same guys who rigged the system get to stay in power," she said.

As far as what Warren is planning to say in Philadelphia, the senator played along with Colbert when he asked what viewers could expect.

"Donald Trump is a bad guy," she said. "I’m going with that."
