Rep. Maxine Waters, D-Calif., said President Trump is "deplorable" and believes he will ultimately be impeached after special counsel Robert Mueller's investigation ends.

"I think he's the most deplorable person I've ever met in my life," she said on MSNBC.

Waters, an early and vocal critic of Trump, said she has "no hope" that new White House chief of staff John Kelly would be able to rein in Trump.

"No," said when asked if Kelly could change Trump. "We've been talking about this president becoming presidential or transitioning long enough. It's not going to happen."

"He is a flawed man with no real values, and no real appreciation or understanding for government or public policy," she added. "No, I have no hope that anybody is going to be able to contain him, or that he's going to change."

Waters has led the charge to impeach Trump, but acknowledged that she has no information about Trump's alleged ties to Russia, and said Mueller has to finish his job before impeachment can happen. But she said Mueller would likely get there.

"I have my hopes in Muller, as most people do," she said. "I think he's going to connect the dots, and I think we're nearing a constitutional crisis."

Waters is hoping that Mueller finds evidence that compels people to push Trump out of office.

"I'm betting on when the dots are connected, and Mueller is able to show collusion, I'm banking on the patriotism of some of the Americans, most of them," she said. "They won't be able to stand with him if it is proven that they colluded, that they undermined our democracy, interfered with our elections."

"They're going to be able to see that this president is dangerous, and I do believe that patriotism will win," she said.

She said she knows even some Republicans are "concerned" and "uncomfortable" with Trump's presidency.

"I have sensed the uneasiness, and I've heard the concern" among Republicans, she said.
