Democrats unveil Trump impeachment charges

The Democratic-controlled US House Judiciary Committee has unveiled charges against President Donald Trump, a key move in impeaching him.

The first article revealed by committee chief Jerry Nadler accuses Mr Trump of abuse of power and the second accuses him of obstructing Congress.

The Republican president is said to have withheld aid to Ukraine for domestic political reasons.

A defiant Mr Trump has urged the Senate to try him “sooner than later”.

“The president wants a trial,” White House spokesman Hogan Gidley told BBC News.

Mr Trump insists he has done “nothing wrong” and has dismissed the impeachment process as “madness”.
