(Washington, DC) — Members of the Senate have been sworn-in as jurors for the impeachment trial of President Trump. Supreme Court Chief Justice John Roberts administered the oath. Roberts will preside over the impeachment trial. The trial will begin in earnest on Tuesday. Roberts was sworn-in by Iowa Republican Chuck Grassley, the Senate pro tempore. Senators then began signing a special impeachment oath book in groups of four.

An hour earlier the Senate formally received the House articles of impeachment against President Trump. House impeachment managers were in the Senate chamber and the two articles of impeachment were read aloud by California’s Adam Schiff. Schiff chairs the House Intelligence Committee. Trump was impeached for abusing power and obstructing Congress in the investigation of the Ukraine scandal. The House impeached the President last month. The Senate trial will determine whether Trump is removed from office.

The other House impeachment managers are California’s Zoe Lofgren, New York’s Hakeem Jeffries, Florida’s Val Demings, Colorado’s Jason Crow, Texan Sylvia Garcia and New York’s Jerry Nadler. Nadler chairs the House Judiciary Committee.
