Attorney General William Barr suggested on Wednesday that the calls for a nationwide lockdown to prevent the spread of the coronavirus were the "greatest intrusion on civil liberties" in history "other than slavery."

The comments came minutes after he slammed the hundreds of Justice Department prosecutors working beneath him, equating them to preschoolers, in a defense of his own politically tuned decision making in the Trump administration.

Addressing a Constitution Day celebration hosted by Hillsdale College, the event's host asked Barr to explain the "constitutional hurdles for forbidding a church from meeting during Covid-19."

The question lead Barr into a four-minute response where he said state governors were using their executive powers to stifle citizens and businesses from going back to work.

"You know, putting a national lockdown, stay at home orders, is like house arrest. Other than slavery, which was a different kind of restraint, this is the greatest intrusion on civil liberties in American history," Barr said as a round of applause came from the crowd.

Covid-19 has taken a measurable toll on minorities, including Black people, according to the Centers for Disease Control and Prevention.

In recent weeks, Barr has taken a much more aggressive stance defending Trump administration policies, including suggesting voting by mail is not safe, attacking the Mueller investigation into Russian meddling in the 2016 election and criticizing governors for their coronavirus response.

"Most of the governors do what bureaucrats always do, which is they ... defy common sense," Barr said Wednesday. "They treat free citizens as babies that can't take responsibility for themselves and others."
