•US President-elect Biden
Two legislators pledged after a White House meeting to follow “normal process” in validating the vote.
Earlier in the day, Georgia dealt Mr Trump another blow by certifying Mr Biden’s razor-thin margin of victory.
The Democrat is set to take office on 20 January as the 46th US president.
Meanwhile, Mr Trump again falsely claimed victory during a White House announcement on drug pricing, dropping in a mention of the election to say: “I won, by the way.”
