BBC News:– All 50 US states and the District of Columbia (DC) are on alert for possible violent protests this weekend, ahead of President-elect Joe Biden’s inauguration on Wednesday.
National Guard troops from across the country are being sent to Washington DC, to discourage any repeat of the deadly riot that unfolded on 6 January.
The FBI has warned of possible armed marches by pro-Trump demonstrators at all 50 state capitols.
The National Mall in DC has been shut.
Barricades are lining the streets of the capital amid tightened security.
Police confirmed on Saturday that a Virginia man had been arrested a day earlier with two handguns and 509 rounds of unregistered ammunition, as he tried to pass through a Capitol Police checkpoint.
He was carrying a “non-government issued credential”, police said.
Responding on Twitter, Representative Don Beyer of Virginia said “the danger is real”, and urged people to avoid the Capitol area.
The Biden team had already asked Americans to avoid travelling to DC for the inauguration because of the Covid-19 pandemic. Local officials said people should watch the event remotely.
Sunday is expected to be a particular focus for protests, after posts on pro-Trump and far-right online networks called for armed demonstrations on that day.
Some militias have told their followers not to attend, however, citing heavy security or claiming the planned events are police traps.
It follows a week in which Donald Trump became the first US president to be impeached twice.
He now faces a Senate trial, on a charge of “incitement of insurrection” linked to the storming of the US Capitol by groups of his supporters.
They did so in a bid to thwart Congress certifying Joe Biden’s victory in the presidential election.
