"Where are the congressional hearings about that? Where is the president of the United States saying, 'Look, stop everybody. I'm the commander in chief. I assume responsibility'?" he continued.

"Stop the blaming. Stop the name calling. We've got to figure out what's going off the rails here, or we're in a big crash. So, that's what's at stake," he said.

The Times published the opinion piece titled “I Am Part of the Resistance Inside the Trump Administration” on Wednesday.

The piece says that administration officials “want the administration to succeed,” but that at the same time they need to work against Trump’s “misguided impulses" and some of his agenda.

The publication said that the person's identity was known to the Times and their "job would be jeopardized" if their name was revealed.

Trump hit back against the op-ed, demanding that the Times turn the author's identity over to the government, calling it a national security issue.

Does the so-called “Senior Administration Official” really exist, or is it just the Failing New York Times with another phony source? If the GUTLESS anonymous person does indeed exist, the Times must, for National Security purposes, turn him/her over to government at once! — Donald J. Trump (@realDonaldTrump) September 5, 2018
