Four people stabbed and one person shot as pro-Trump supporters and opponents clash
Trump has repeatedly, and baselessly, claimed the election was stolen from him through election fraud.
Violent clashes between pro-Donald Trump protesters and counter protestors in the US ended in bloodshed on Saturday.
Thousands of Trump supporters marched in Washington and several state capitals on Saturday to protest what they contended, despite all evidence suggesting otherwise, was a stolen election.
The protestors were angered by a recent Supreme Court ruling which rejected a lawsuit by Texas that had asked the court to throw out the election results in four battleground state.
At least four people were stabbed and are said to be in critical condition amid post-election protests in Washington, the DC Metropolitan Police Department's public affairs office said.
Two police officers were also taken to the hospital with non-life-threatening injuries.
Police said that a shooting had taken place after clashes near the capitol building in Olympia, and that a suspect had been detained.
The condition of the shooting victim is not yet known.
At least 23 people have been arrested for a variety of charges including simple assault, assault on a police officer, riotous acts, crossing a police line and for possession of a prohibited weapon (a stun gun).
