In an interview published Sunday, former Attorney General William Barr bashed former President Donald Trump’s efforts to spread misinformation about the 2020 election, calling Trump’s lies about voter fraud “bullshit.”

Barr, speaking to ABC News’ Jonathan Karl for The Atlantic, opened up about his final few months working under Trump, when the president pushed the Justice Department to investigate baseless allegations of election fraud in an attempt to overturn Joe Biden’s legitimate victory.
