William Barr steps down as Trump's attorney general

• Barr had dismissed Trump's claims of significant voter fraud
• Critics said he made justice department tool of White House

The US attorney general, William Barr, one of Donald Trump's staunchest allies, has resigned just weeks after he contradicted the president by saying the justice department had uncovered no evidence of widespread voter fraud that could change the outcome of the 2020 election.

Barr's departure ends a tenure marked by brazen displays of fealty to a president whose political agenda he willingly advanced. Critics said Barr had turned the Department of Justice (DoJ) into an obedient servant of the White House, eroding its commitment to independence and the rule of law.
