Democrats in the US House of Representatives have taken Republican President Donald Trump to the brink of impeachment by approving two charges against him over his efforts to pressure Ukraine to investigate Democratic political rival Joe Biden.

A divided House Judiciary Committee on Friday voted 23-17 along party lines to approve articles of impeachment charging Mr Trump with abusing the power of his office over the Ukraine scandal and obstructing House Democrats’ attempts to investigate him for it.

Mr Trump is expected to become the third US president to be impeached when the full Democratic-led House votes on the charges, likely next week, setting up a trial in the Republican-controlled Senate.

Mr Trump’s fellow Republicans have shown no signs of wanting to remove him from office.

In congressional hearings that have gripped Washington, Democrats accused the president of endangering the US Constitution, jeopardising national security and undermining the integrity of the 2020 election by asking Ukrainian President Volodymyr Zelenskiy in a July phone call to investigate Biden.

“Today is a solemn and sad day,” said Representative Jerrold Nadler, the judiciary committee’s Democratic chairman.

“For the third time in a little over a century and a half, the House Judiciary Committee has voted articles of impeachment against the president.”

Republicans have defended Mr Trump and accused Democrats of a politically motivated farce aimed at overturning his surprise 2016 presidential election victory.

“Impeachment is a hoax. It’s a sham,” Mr Trump told reporters at the White House after the committee’s vote.

“There was nothing done wrong. To use the power of impeachment for this nonsense is an embarrassment to this country.”

It’s not fair that I’m being Impeached when I’ve done absolutely nothing wrong! The Radical Left, Do Nothing Democrats have become the Party of Hate. They are so bad for our Country!

If impeached, Mr Trump is due to go on trial in the Senate in January just as the 2020 presidential campaign, in which he is seeking re-election, picks up speed.

He said he thought Americans “are absolutely disgusted” with the process, but that it was benefiting him.

“It’s a very sad thing for our country, but it seems to be good for me politically,” Mr Trump said.

Mr Biden, a former US vice president, is a leading Democratic candidate to face Mr Trump in the November 3 election.

Mr Trump has alleged that Mr Biden was involved in corruption in Ukraine and should be investigated there, but has offered no evidence. Biden has denied wrongdoing.
