President Donald Trump appears to be taking his intimidation of the federal judiciary to a new level, telling reporters that he plans to attend Supreme Court arguments for a case on birthright citizenship on Wednesday.

“I’m going,” he said Tuesday. “I think so, I do believe.”

Trump’s attendance at oral arguments was also included in the schedule the White House Office of Communications sent reporters on Tuesday evening.

According to NBC News, the Supreme Court and the nonprofit Supreme Court Historical Society said there was no record of a sitting president ever attending such arguments before.

Trump also floated attending oral arguments at the Supreme Court in a case involving his tariffs, though he ultimately decided against going. When the justices ruled against him earlier this month and struck down his sweeping tariffs, Trump lashed out, accusing the conservative justices who signed the decision of disrespecting him.
