The US president speaks publicly for the first time since the election was called for Joe Biden.
Trump supporters spoke to the BBC's Jane O'Brien in Washington DC.
Supporters of US President-elect Joe Biden give their message to people who voted for Donald Trump.
As night fell on election day, with polls closing and votes being tallied, protests against President Trump were held on the streets of Washington DC, leading to tense scenes.
Hundreds marched through parts of the Capitol, sometimes blocking traffic and setting off fireworks. Some chanted: “If we don’t get no justice, they don’t get no peace!”
The demonstrations were largely peaceful, but there were reports of skirmishes and confrontations outside the White House. Three people were arrested after scuffles, NBC Washington reported.
CBS News reporter Christina Ruffini tweeted that "some sort of smoke bomb" appeared to have been used.
Elsewhere, there were reports of scattered protests in Los Angeles, California; Raleigh, North Carolina; Portland, Oregon and New York City.

Trump has taken the podium in the White House's East Room.
He starts by thanking his family, and the millions of supporters who turned out for him tonight.
"We were getting ready for a big celebration," he says. "We were winning everything."
Taking a triumphant tone, Trump celebrates his big win of the night in Florida.
"We didn't win it, we won it by a lot," he says.
He also claims a lead in Pennsylvania - just like rival Joe Biden did earlier on election night. It is still too early to determine a winner in the state.
