RNA - In a series of tweets on Thursday, the Republican president attacked Pelosi, the most senior Democrat in Congress, describing her congressional district in California as "filthy dirty" and "one of the worst anywhere in the US."
Trump also celled Pelosi "crazy" and suggested another California Democrat should challenge Pelosi in next year's congressional election.
"The Radical Left, Do Nothing Democrats said they wanted to RUSH everything through to the Senate because 'President Trump is a threat to National Security' (they are vicious, will say anything!), but now they don't want to go fast anymore, they want to go very slowly," Trump tweeted. "Liars!"
"Bad for USA!" he wrote.
The president also claimed the "bogus impeachment scam" made it more difficult for him to negotiate with foreign leaders.
Trump was impeached last week by the Democratic-led House of Representatives on two charges of abuse of power and obstructing Congress’ investigation.
The impeachment probe was launched in September over his pressuring Ukraine to announce an investigation of former Vice President Joe Biden, one of the top contenders for the Democratic presidential nomination, and Biden’s son.
Trump has said he did nothing wrong.
Impeachment begins in the House. If the lower chamber of Congress approves articles of impeachment, a vote is then held in the Senate. A two-thirds majority vote would be needed in the Senate to remove the president from office.
Pelosi and Senate Majority Leader Mitch McConnell, a Republican from Kentucky, have been disagreeing over the ground rules for Trump’s Senate trial. Republicans have a 53-seat majority in the Senate, where 51 votes are needed to pass a set of rules for the Trump trial.
There is little chance Trump will be convicted and removed from office through a trial in the Republican-led Senate, but the impeachment proceedings could resonate at the ballot box in November.
