Speaker Nancy Pelosi on Wednesday named two House chairmen who led President Donald Trump’s impeachment inquiry as prosecutors for Trump’s Senate trial.

Intelligence Committee Chairman Adam Schiff, who led the probe, and Judiciary Chair Rep. Jerrold Nadler, whose committee approved the impeachment articles, as among the managers of the prosecution.

“Today is an important day,” said Pelosi, flanked by the team. “This is about the Constitution of the United States.”’

Schiff and Nadler will lead the seven member team that includes a diverse selection of lawmakers, particularly those with courtroom experience.

They include Hakeem Jeffries of New York, Sylvia Garcia of Texas, Val Demings of Florida, Jason Crow of Colorado and Zoe Lofgren of California.

During Pelosi’s press conference, Trump tweeted that impeachment is “another Con Job by the Do Nothing Democrats. All of this work was supposed to be done by the House, not the Senate!”

Trump was impeached by the Democratic-led House last month on charges of abuse of power over his pressure on Ukraine to investigate Democratic rival Joe Biden as Trump withheld aid from the country. He was also charged with obstructing Congress’ ensuing probe.

The House is set to vote later in the day to send the articles of impeachment to the Senate for a trial on whether the charges of abuse of power and obstruction of Congress are grounds for his removal. The managers will walk then walk the articles across the Capitol to the Senate.

Trump’s trial will be only the third presidential impeachment trial in U.S. history, and it comes against the backdrop of a politically divided nation and an election year.

New details of Trump’s efforts on Ukraine emerged late Tuesday, increasing pressure on senators to call witnesses in the trial, a step that Senate Majority Leader Mitch McConnell has been reluctant to take.

House investigators announced they were turning over a “trove” of new records of phone calls, text messages and other information from Lev Parnas, an associate of Trump lawyer Rudy Giuliani. Intelligence Committee Chairman Adam Schiff said the information shows Trump’s effort ’’to coerce Ukraine into helping the President’s reelection campaign.” He said this and other new testimony must be included in the Senate trial.
