Donald Trump has become the third president in US history to be impeached.
The House of Representatives voted to impeach on both charges of abuse of power and obstruction of Congress.
Mr. Trump denies putting pressure on Ukraine to investigate a political rival, but Democrats think he should face a trial in the Senate.
Ultimately Mr. Trump has enough support in the Senate that he probably won't be removed from office.
The President sent this tweet after hearing the news that he had been impeached.
