US President Donald Trump has blasted calls to impeach new Supereme Court judge Brett Kavanaugh, labelling the claims against him as a “hoax”.

In Mr Trump’s boldest attempt yet to defend his new appointee the President said the sexual assault allegations levelled against him were “all made up”.

As Americans prepare to head to the polls on November 6 for the mid term elections, some Democrats have suggested impeaching Mr Kavanaugh, but Mr Trump rejected the notion.

Departing the White House for an event in Florida, Mr Trump told reporters that any attempt to remove Mr Kavanaugh from the highest judicial position in the country would be an “insult to the American public”.

“The American public has seen this charade, has seen this dishonesty by the Democrats,” Mr Trump added.

He described Mr Kavanaugh as a “a brilliant juris, a man that did nothing wrong”, saying the sexual assault claims made against him by multiple women were nothing more than a Democratic “hoax”.

Mr Trump also said that Mr Kavanaugh was a “top scholar, top student, top intellect”.

Mr Trump said the Democratic’s will ultimately pay a high price for their partisanship.

“I think you’re going to see a lot of things happen on November 6th that would not have happened before. The American public has seen this charade,” Mr Trump said.

“I think a lot of Democrats are going to vote Republican.

The main base of the Democrats have shifted so far left that we’ll end up being Venezuela. This country would end up being Venezuela.”

Mr Kavanaugh was formally sworn in as Supreme Court justice at a private ceremony on Saturday.

Thousands of anti-Kavanaugh protesters raged outside the Supreme Court steps that evening to vent their frustration at the confirmation.

Mr Kavanaugh will undergo another public swearing-in ceremony at the White House on Monday evening.
