Donald Trump unleashed on New York Times columnist Paul Krugman, as well as the newspaper itself, accusing the liberal opinion writer and economist of being “obsessed with hatred” of his administration.

In a pair of tweets, Trump ripped Krugman for what he called “false and highly inaccurate writings” following Krugman’s most recent column, which said Republicans no longer support American values.

“Paul Krugman, of the Fake News New York Times, has lost all credibility, as has the Times itself, with his false and highly inaccurate writings on me,” Trump wrote. “He is obsessed with hatred, just as others are obsessed with how stupid he is. He said Market would crash, Only Record Highs!”

“I wonder if the New York Times will apologize to me a second time, as they did after the 2016 Election,” Trump continued. “But this one will have to be a far bigger & better apology. On this one they will have to get down on their knees & beg for forgiveness—they are truly the Enemy of the People!”

Trump’s criticism followed Krugman’s accusation that the president and his campaign “welcomed” Russian assistance during the 2016 election, a reference to findings in special counsel Robert Mueller’s report that determined Russian operatives interfered in the 2016 election with the intent of supporting Trump’s candidacy.

“A hostile foreign power intervened in the presidential election, hoping to install Donald Trump in the White House. The Trump campaign was aware of this intervention and welcomed it. And once in power, Trump tried to block any inquiry into what happened,” Krugman wrote.

Trump’s suggestion that the NY Times needs to “get down on their knees & beg forgiveness” is a curious turn of phrase that does nothing to dismiss the mafia-style management style that has colored his presidency.

Trump has received a lot of criticism for what many see is the unsafe and Stalinist use of the term “Enemy of the People,” particularly as there have been legitimate threats of violence threated against many members of the press, in particular by individuals who identify as Trump supporters.
