United States Of America, for the third time in their history has has impeached a sitting president, Donald Trump.
This occurred when the House of Representatives voted to impeach a sitting president, following a day-long debate on whether Trump violated his oath in pressuring Ukraine to damage a political opponent.
Trump was impeached on two articles. The 230-197 vote to impeach him for abuse of power was almost entirely on party lines and was followed quickly by a second vote that the president obstructed Congress.
