WASHINGTON — Trying to repair his tarnished legacy, President Donald Trump trumpeted his administration’s accomplishments and wished his successor luck in a farewell video as he spent his final full day in office preparing to issue a flurry of pardons in a near-deserted White House, surrounded by an extraordinary security presence outside.

“This week we inaugurate a new administration and pray for its success in keeping America safe and prosperous,” Trump said in the video “farewell address,” released by the White House less than 24 hours before President-elect Joe Biden’s inauguration. “We extend our best wishes. And we also want them to have luck — a very important word.”

Trump, who spent months trying to delegitimize Biden’s win with baseless allegations of mass voter fraud, repeatedly refenced the “next administration,” but declined to utter Biden’s name. Many of Trump’s supporters continue to believe the election was stolen from him, even though a long list of judges, Republican state officials and even Trump’s own government have said there is no evidence to support that claim.

Trump has remained largely out of sight since his supporters stormed the Capitol building earlier this month, trying to halt the peaceful transfer of power.
