The US House Judiciary Committee has said it will begin hearings on 4 December in the next phase of the impeachment inquiry into Donald Trump, inviting the US president and his lawyer to attend.

Politicians in the Democratic-led House of Representatives spent the last two weeks publicly questioning witnesses, including White House officials and diplomats, over allegations Mr Trump abused the power of his office when he pressured Ukraine to launch investigations that would help him politically.

With that stage complete, the Judiciary Committee is now tasked with considering whether to draft articles of impeachment against the president.

In a letter to President Trump, Judiciary Committee chairman Jerry Nadler said: "The committee looks forward to your participation in the impeachment inquiry as the committee fulfills its constitutional duties."

The hearings will address "the historical and constitutional basis of impeachment," and "whether your alleged actions warrant the House exercising its authority to adopt articles of impeachment," he added.

Under procedural rules passed by the House last month, Mr Trump is invited to attend the judiciary committee hearings, and "the president's counsel may question any witness called."

In the letter, Mr Trump is reminded that if he continues to refuse to allow administration personnel to testify or turn over documents sought by the inquiry, the chair may "impose appropriate remedies," including denying presidential requests to question witnesses.

Democrats leading the probe have said they could present their report detailing presidential wrongdoing as early as next week, when Congress reconvenes after the Thanksgiving break.

House Intelligence Committee chairman Adam Schiff presided over two weeks of dramatic public hearings that he said uncovered a "massive amount of evidence" despite efforts to obstruct the investigation by Mr Trump and his administration.

Mr Schiff said the evidence "conclusively shows" that Mr Trump made a White House meeting with Ukraine's new president and critical US military assistance conditional on Kiev announcing investigations that would help Mr Trump's 2020 re-election campaign.

Those include a probe of a Ukrainian energy company where Hunter Biden, the son of Mr Trump's potential election rival Joe Biden, sat on the board.

Mr Trump in recent months has repeatedly described the Bidens as "corrupt" despite no evidence of the family committing any wrongdoing related to Ukraine.

The remaining transcripts from closed-door impeachment interviews were released yesterday - including testimony from Mark Sandy, a career official in the White House's budget office, who said an attorney at the office had resigned in part due to concerns over the hold on military aid to Ukraine.
