BRANCHBURG, N.J. — President Trump, back at the Bedminster, N.J., golf getaway where he decided to fire James B. Comey, took his harshest shot yet against his former F.B.I. director on Sunday morning, calling him “cowardly” and vowing to find out if he had leaked any more sensitive information.
“I believe the James Comey leaks will be far more prevalent than anyone ever thought possible,” Mr. Trump wrote in one of his patented early morning Twitter tirades — fulfilling the expectations of staff members who had feared he would lash out after spending a sunny weekend watching replays of Mr. Comey calling him a liar.
I believe the James Comey leaks will be far more prevalent than anyone ever thought possible. Totally illegal? Very ‘cowardly!’
“Totally illegal?” Mr. Trump asked rhetorically about Mr. Comey’s leaks of his private conversations with the president, including one in which he said Mr. Trump pressed him to drop an investigation into Michael T. Flynn, the former national security adviser.
“Very cowardly!” the president tweeted in response to his own query.
At a news conference on Friday, Mr. Trump had refused to directly say whether Mr. Comey lied to Congress in his testimony on Thursday. After brushing aside that question, he ignored the same question when it was shouted at him by reporters as he boarded Air Force One en route to New Jersey.
