The House on Wednesday delivered articles of impeachment against President Trump to the Senate and approved seven Democrats to serve as prosecutors in the third trial of a U.S. president.

House Speaker Nancy Pelosi (D-Calif.) signed the articles at a ceremony in the Capitol, hours after she named a team of managers led by two trusted lieutenants, Intelligence Committee Chairman Adam B. Schiff (D-Calif.) and Judiciary Committee Chairman Jerrold Nadler (D-N.Y.).

The managers then walked the articles across the Capitol and presented them to the chamber led by Senate Majority Leader Mitch McConnell (R-Ky.), who has repeatedly characterized the House case as weak.

The crux of the case is the allegation that Trump tried to leverage a White House meeting and military aid, sought by Ukraine to combat Russian military aggression, to pressure Ukrainian President Volodymyr Zelensky to launch an investigation of former vice president Joe Biden and his son Hunter Biden, as well as a probe of an unfounded theory that Kyiv conspired with Democrats to interfere in the 2016 presidential election.
