Democrats in the House of Representatives announced formal charges against President Donald Trump on Tuesday that accuse him of abusing power and obstructing Congress, making him only the fourth US president in history to face impeachment.

The full Democratic-controlled House is expected to vote on the charges, or articles of impeachment, next week. It is almost certain to vote to impeach the Republican president, setting the stage for a dramatic trial in the Republican-controlled Senate, likely to begin in January.
