Ever since the op-ed was published on Wednesday, the White House has been working to identify the culprit who wrote that there's a "resistance" inside the administration working to thwart the president's "worst inclinations".
Trump continued attacking the op-ed yesterday, suggesting to Fox & Friends that by publishing the piece, the Times is "virtually" guilty of "treason". "[Donald Trump] has a clear governing vision for the country and his record of results is remarkable".
Trump would be far from the first president to hunt for leakers.
You can't even give coherent speech, ' wrote one critic.
Let's just hope this saga doesn't end like this.
After the piece was published, Trump took to Twitter saying, "If the GUTLESS anonymous person does indeed exist, the Times must, for National Security purposes, turn him/her over to government at once!"
The Pentagon said Defense Secretary James Mattis did not write the piece.
Advised the tests would result in mass resignations, he ordered the tests for about 1,000 employees of the State and Defense departments, the Central Intelligence Agency and the National Security Council.
"People talk about the loyalists leaving", the person close to Trump said. "I think their reporters should go and investigate who it is", Trump told the crowd.
"I stole it off his desk", Cohn reportedly said.
Drawing on hundreds of hours of interviews, the respected White House chronicler describes a coalition of like-minded aides plotting to prevent the USA president from destroying the world trade system, undermining national security, and sparking wars.
Trump had threatened to sue the Times when he was running for president in October 2016 because of its story about allegations of sexual assault against women.
"It's a disgrace that somebody can do that", Trump said.
Hindustan Times, owned by HT Media Ltd, is one of India's largest publications that provides unbiased news, analysis and features on politics, sports, entertainment, lifestyle and more.
Trump pointed out the number of his senior officials who denied being the author of the op-ed.
The Department of Justice said in response: "The department does not confirm, deny or otherwise acknowledge the existence or non-existence of investigations". A wounded lion is a very unsafe animal, and I think Donald Trump is wounded.
