Donald Trump accuses democrats of witch-hunt

US president Donald Trump has once again accused democrats of launching a witch hunt against him.

He said the move would help him get re-elected.

Trump spoke on Tuesday after the long-anticipated formal impeachment against him was announced by the democrat-led house of representatives.

In the two articles of impeachment, house democrats accused the republican president of abuse of power and obstruction of congress.

Trump denies having done anything wrong and has called the impeachment probe a hoax.
