Sen. Kamala Harris (D-Calif.) said the Justice Department would have “no choice” but to charge President Donald Trump with obstruction of justice if he finished his term without being impeached.

Speaking with NPR’s Scott Detrow in an interview published Wednesday, Harris said special counsel Robert Mueller essentially set the stage for criminal charges against Trump with his investigation into the 2016 election. Longstanding Justice Department policy says that a sitting president cannot be indicted, and Harris said that was essentially the only reason Mueller did not charge Trump.

All that would change in 2021 if the Democratic presidential hopeful were in the White House and the Justice Department were under her watch, she said.

“I believe that they would have no choice, and that they should,” Harris said of the Justice Department’s charging Trump with obstruction. “I believe there should be accountability. Everyone should be held accountable. And the president is not above the law.”
