President Donald J. Trump was impeached on Wednesday.

For the third time in the nation’s history, the House of Representatives voted to impeach a sitting president, acting after a daylong debate on whether Trump violated his oath in pressuring Ukraine to damage a political opponent.

Trump was impeached on two articles. The first vote, 230-197, accused him of abuse of power and was almost entirely on party lines; it was followed quickly by a second, 229-198, vote accusing the president of obstructing Congress. The one-vote difference was that of Democrat Jared Golden of Maine, who voted yes on abuse of power and no on obstruction.
