The US Department of Defense has formally activated thousands of National Guard troops ahead of President-elect Joe Biden's inauguration in two weeks' time.
Roughly 6,200 members of the force have been called in from the six most north-eastern states to help support the Capitol Police and other law enforcement in Washington.
Acting US Defense Secretary Christopher Miller signed orders activating the members of the National Guard for up to 30 days, with the personnel arriving over the next few days.
The National Guard will not be armed, but members will reportedly be equipped with riot gear and protective clothing to help prepare for any further civil unrest.
Although a total of 6,200 have been activated, the exact number of troops that will actually get to the city may be less than that, depending on who is available in each state.
It comes a day after National Guard troops were deployed to the US Capitol as armed protestors broke into the building, forcing Congress members to halt the ongoing vote to certify Mr Biden’s election and then flee from the House and Senate chambers.
Four people died in the melee, including a protester who was shot by police.
The vote was later completed after the building was cleared.
The FBI is now in the process of identifying those involved in the riot, which came after President Donald Trump held a rally and told the crowd he would never concede and urged them to march to the Capitol.
US Capitol Police confirmed on Thursday that an officer who was hurt after responding to the riots had died from his injuries.
