President Trump appeared to mock House Speaker Nancy Pelosi during a press conference ahead of the impeachment vote this week, saying her teeth were "falling out of her mouth". In the coming days, the House of Representatives is expected to impeach the president over two articles in relation to his alleged misconduct with Ukraine, namely abuse of power and obstructing Congress, the Independent reports.

Trump's comments came after Pelosi was asked by a reporter why the Democrats did not include "bribery" as one of the articles of impeachment, especially after she used that term to describe the president's actions.

In response, Pelosi claimed the decision was made following a discussion with House committee chairs and attorneys. This prompted Republican Rep. Mark Meadows to claim that the bribery article was not included simply because "it wasn't true".

That said, Trump offered a different perspective on the House Speaker's response. According to him, her answer was “because Nancy’s teeth were falling out of her mouth, and she didn’t have time to think".

The president's remarks are the latest in a barrage of personal attacks leveled against Pelosi.

Previously, Trump has accused the senior Democratic Congresswoman of being “unhinged” and called her efforts to impeach him a partisan attack on his administration.

Meanwhile, Democratic Rep. David Cicilline chimed in to suggest that Trump was targeting Pelosi because she is a senior woman in politics.

“These are serious times & he’s spent the last week attacking strong women [such as] @GretaThunberg, @RepDebDingell and @SpeakerPelosi," Cicilline tweeted on December 15.

But Republican Rep. Mike Johnson appeared to play down the attack when asked about it on CNN, saying Trump was merely "frustrated" at the prospect of becoming only the third president to be impeached in US history.

“The president has a very unorthodox style of messaging. It’s not the way that I talk or I would tweet,” Johnson said. “But the president is very frustrated about how he's been treated. He lashes out sometimes and I think a lot of the American people understand that."
