The US president has been told he is welcome to be represented on 4 December, once the country goes back to work after its Thanksgiving break.
Jerrold Nadler, the Democratic chairman of the House Judiciary Committee that is leading the inquiry, says it’s the president’s choice.
Mr Nadler said in a statement: “The president has a choice to make, he can take this opportunity to be represented in the impeachment hearings or he can stop complaining about the process.
“I hope that he chooses to participate.”
The Democrat has also written a letter to the president reminding him he is welcome to attend the hearing next week, which marks the next stage of a probe into a phone call between Mr Trump and his Ukrainian counterpart.
It is alleged that Mr Trump abused his power by asking Volodomyr Zelenskiy to investigate Joe Biden, who is the favourite to be selected as the Democrat candidate for the presidential election next year.
Mr Trump is also accused of requesting an investigation into the former vice president’s son Hunter Biden, who had previously worked for the Ukrainian energy company Burisma.
The president has repeatedly asserted he did nothing wrong and has dismissed the inquiry as a “witch hunt”, but has indicated that he could be willing to give evidence at the hearings.
