The US House of Representatives will vote later to impeach President Trump on charges of inciting his supporters to storm the Capitol last week.

The vote is expected to pass in the Democrat-led House, which would make him the first US president to be impeached twice.

Democrats accuse the president of encouraging his supporters to attack the Capitol building. Five people died.

Members of Mr Trump's Republican party say they will join Democrats to impeach him on Wednesday, formally charging the president with inciting insurrection.

President Trump has rejected any responsibility for the violence.

The riot last Wednesday happened after Mr Trump told supporters at a rally in Washington DC to "fight like hell" against the result of November's election.

As Democrats hold a majority in the House, the vote is likely to pass. The case will then head for the Senate, where a trial will be held to determine the president's guilt.

A two-thirds majority would be needed to convict Mr Trump, meaning at least 17 Republicans would have to vote for conviction. As many as 20 Senate Republicans are open to convicting the president, the New York Times reports.

The timeline of when a trial could be held is not known but it is unlikely it could be finished before Mr Trump leaves office on 20 January, when Joe Biden will be sworn in as president.

The Senate could also use an impeachment trial to hold a vote blocking Mr Trump from ever running for office again. He has indicated he plans to campaign for president in 2024.
