Disputing President Donald Trump's persistent, baseless claims, Attorney General William Barr declared the US Justice Department has uncovered no evidence of widespread voter fraud that could change the outcome of the 2020 election.

Barr's comments, in an interview on Tuesday with the The Associated Press, contradict the concerted effort by Trump, his boss, to subvert the results of last month's voting and block President-elect Joe Biden from taking his place in the White House.
