"Two things are true and clear," said the mayor of South Bend, Indiana. "One: nobody is above the law, and two: the prosecution process should have nothing to do with politics – the less it has to do with the president, the better."
Harris said that she expected the Justice Department to sue Trump if she or any Democrat beat him in 2020.
Buttigieg argued that if Trump's behavior would likely result in substantive litigation, the Department of Justice, not the White House, should make that decision.
"At the moment, we have a president who seems to think that the president can only dictate what the DOJ will do, ask for political opponents to be jailed," Buttigieg told Tapper. "I think that the rule of law will catch up with this president.It is not necessary for the oval office to get their hands dirty".
He added, "I'm counting on the GM to make the right decisions, at least on the GM that I would name and organize, and the fewer White House directives there are, the better."
When asked if he disagreed with Harris, Buttigieg said that he "was just talking about how I see the issue".
"But, again, I think we can maintain these two principles: that no one is above the law and that the decisions of the lawsuits must have nothing to do with politics and must come from the DOJ himself, not from the Oval, "he said.
Although the commentary appears to contradict what the mayor said to Tapper, Atlantic later wrote in the same article that "Buttigieg said he would be wary of asking his Attorney General to actively pursue the President against Tapper. President".
