President Donald Trump lashed out on Twitter on Tuesday against Democratic California Rep. Maxine Waters who called for the impeachment of both the POTUS and Vice President Mike Pence during a speech in Los Angeles over the weekend.

“Crazy Maxine Waters: ‘After we impeach Trump, we’ll go after Mike Pence. We’ll get him.’ @FoxNews Where are the Democrats coming from? The best Economy in the history of our country would totally collapse if they ever took control!” Trump tweeted.

On Saturday, Waters took the stage to accept a lifetime achievement award from the Stonewall Young Democrats in Los Angeles, and that was when she renewed calls for the president’s impeachment, despite claiming that members of her party did not want her to bring up the issue.

“And, as you know, there’s a difference in how some of our leadership talk about how we should handle all of this,” she said. “They say, ‘Maxine, please don’t say impeachment anymore. ‘And when they say that, I say, ‘Impeachment, impeachment, impeachment, impeachment, impeachment, impeachment, impeachment, impeachment." 

After taking a jab at Trump, she also went after Pence. “I had a conversation here today with someone [who] asked, ‘Well, what about Pence? If you are able to impeach, Pence will be worse,’” Waters said. “And I said, ‘Look, one at a time. You knock one down, one at a time. You knock one down, and we’ll be ready for Pence. We’ll get him, too.”

“We cannot be intimidated,” Waters continued. “We cannot be made to fear anybody who would undermine our ability to have a decent quality of life.”

Back in August, Trump said in an interview with “Fox & Friends” that impeaching him would only lead to the market crashing and everyone becoming poor.

“I don’t know how you can impeach somebody who’s done a great job,” Trump said in response to a question from Fox News' Ainsley Earhardt, who asked if he believes Democrats would try to impeach him if they win back control of Congress in the midterms. "You know, I guess it says something like high crimes and all -- I don't know how you can impeach somebody who has done a great job.”

“If I ever got impeached, I think the market would crash, I think everybody would be very poor, because without this thinking, you would see — you would see numbers that you wouldn’t believe in reverse,” he added.

The idea to impeach Trump resurfaced after president's former attorney, Michael Cohen, implicated him while pleading guilty to a felony charge, saying the POTUS had asked him to use campaign money to arrange payments to two women — adult film star Stormy Daniels and former Playboy model Karen McDougal — both allegedly had affairs with the president.

"This is all they (Democrats) need for impeachment," Michael Caputo, a former Trump adviser told CNN in August. "If the Democrats take over the House during the midterm elections, this indication coming out of the Southern District of New York, this charge, is enough for them to run an impeachment against the president, even in the first quarter."
