U.S. President Donald Trump on Monday said he would support the arrest of California Governor Gavin Newsom over possible obstruction of his administration's immigration enforcement measures amid protests in the state.

As he returned to the White House today, Trump was asked if border czar Tom Homan should arrest California Gov. Gavin Newsom, as Newsom has dared him to do. “I would do it if I were Tom,” Trump told reporters. “I think it’s great. Gavin likes the publicity.” He added: “I like Gavin Newsom, he’s a nice guy, but he’s grossly incompetent.”

The dare and double-dare between Newsom and the Trump administration comes after the president ordered the National Guard into Los Angeles.
