Democrats in the House of Representatives unveiled two articles of impeachment against Donald Trump on Tuesday, accusing the US president of abusing power and obstructing Congress.

The move sets Mr Trump on course to be just the third president in US history to be impeached by the full House when the 'articles' are put to vote next week.

Speaking behind a wooden panel draped in American flags, the House Speaker Nancy Pelosi and the heads of six investigative committees said they had come to the "solemn" decision after months of investigation.

“We must be clear: no one, not even the president, is above the law,” said Jerry Nadler, the chair of the Judiciary Committee, as he announced the proposed articles of impeachment.

The first article charges Mr Trump with abusing his power by putting his political concerns over America's national interest.
