House Intelligence Committee Chairman Adam Schiff and Judiciary Committee chairman Jerrold Nadler will be part of the team announced on Wednesday, Presstv Reported.
Pelosi named Schiff the "lead" impeachment manager. She highlighted Schiff separately as "lead manager" in a statement issued during the announcement.
“It is their responsibility to present the very strong case for the President’s impeachment and removal," Pelosi said in the statement.
Others picked for the high-profile role of managers include Democratic Reps. Hakeem Jeffries, Zoe Lofgren, Val Demings, Sylvia Garcia, and Jason Crow.
The group will serve as the public face of the impeachment process. They are expected to carry the two articles of impeachment over to the Senate chamber late Wednesday.
Democrats have also unveiled new evidence that they plan to submit to the Senate as part of the case.
Trump derides impeachment trial as a 'con'
Seconds after Pelosi unveiled the seven-member trial team, in a tweet, Trump derided his impeachment as a “con.”
"Here we go again, another Con Job by the Do Nothing Democrats," Trump tweeted.
Senate Majority Leader Mitch McConnell announced on Tuesday the impeachment trial will begin next Tuesday, January 14.
He said he expected the House to send the articles of impeachment through to the upper chamber on Wednesday.
A two-thirds majority vote would be needed in the Senate to remove the president from office. With Republicans in control of the upper chamber, Trump’s acquittal in a trial seems certain.
House Democrats launched the inquiry against Trump in September after an unknown whistleblower alleged the Republican president pressured his Ukrainian counterpart to investigate former Vice President Joe Biden and his son Hunter, who had served as a director for Ukrainian energy company Burisma.
Democrats are looking into whether Trump abused his power by withholding $391 million in US security aid to Ukraine in exchange for the investigation.
Trump has repeatedly denounced the impeachment inquiry against him as “a hoax.”
