President Trump’s former attorney Michael Cohen blasted the chief executive’s COVID-19 diagnosis Friday, claiming that the White House is to blame.

“Trump is now COVID-positive because of ignorance and arrogance,” Cohen told reporters from the BBC and his homedown Daily News.

He argued that more testing and other resources at Trump’s disposal could have prevented the spread of the coronavirus to the president, first lady and a number of other people close to the White House.

Other people infected include senior adviser Hope Hicks; campaign manager Bill Stepien; former N.J. Gov. Chris Christie, who helped prep the president for this week’s debate with 2020 Democratic nominee Joe Biden; and at least three GOP senators.

TRUMP TESTS POSITIVE FOR CORONAVIRUS: HERE'S WHO ELSE IS POSITIVE, AND WHO'S NEGATIVE

Cohen  called the president “reckless” for not taking more precautions.

“This whole situation is tragic in that this was all preventable,” he said.

Cohen was previously a staunch Trump ally before turning on the president, even as he was convicted of campaign finance violations and other crimes stemming from his work on the Trump campaign. He was released from prison on July and is serving the rest of his 3-year sentence in home confinement in his New York City abode.

President Trump was flown to Walter Reed Medical Center Friday evening aboard the Marine One helicopter. He spent the night there and was “doing very well” as of Saturday afternoon, with no difficulty breathing. But an administration official warned that the next 48 hours would be “critical” to the president’s progress.

TRUMP'S MEDICAL TEAM SAYS HE IS DOING 'WERY WELL;' OFFICIAL WARNS NEXT 48 HOURS ARE 'CRITICAL'

White House physician Dr. Sean Conley and other members of the medical team briefed reporters on Trump’s condition. Conley said they were “extremely happy with the progress” Trump is making.

But a senior administration official told Fox News that on Friday morning, the president exhibited signs of a possible progression from mild to more severe illness.

“Twenty-four hours ago, there was real concern about the President’s vitals," the official said. "For the past 12 hours, there has been zero concern.”
