When Speaker Nancy Pelosi was putting together her list of prosecutors who would build the House Democrats’ case for removing President Trump from office, she set her eyes on two New Yorkers: Representatives Jerrold Nadler and Hakeem Jeffries.

Mr. Nadler, the chairman of the House Judiciary Committee, has been a thorn in Mr. Trump’s side since the 1990s. Mr. Jeffries is known as one of the Democrats’ top messengers; his rhetorical skills were honed while working at a corporate law firm in New York.

The congressmen are among the seven impeachment managers who will help take the case to the Senate.

What the congressmen will be doing

Mr. Nadler and Mr. Jeffries will play the role of prosecutors in the impeachment trial, which will be overseen by Chief Justice John G. Roberts Jr. The Senate will act as the jury.

Mr. Nadler will be the impeachment managers’ constitutional expert.

Essentially, the managers will argue in favor of Mr. Trump’s removal from office. The president, who is accused of abusing his power for his own political gain and obstructing Congress, has called the impeachment inquiry a “witch hunt” and a “sham.”
