President Donald Trump on Friday resumed his attacks on journalists, calling one a loser, accusing another of asking a stupid question and defending a video shared by White House press secretary Sarah Huckabee Sanders that appeared to have been doctored to cast CNN reporter Jim Acosta in a negative light.

Sanders circulated the video Wednesday night after the White House announced it had revoked Acostas press credentials following a contentious press conference with the president.

No one manipulated it, give me a break, Trump told reporters outside the White House.

Sanders claimed the video proves Acosta became aggressive with a White House intern attempting to take a microphone from him. In a tweet, she said the Trump administration will never tolerate a reporter placing his hands on a young woman just trying to do her job as a White House intern.

But multiple outlets consulted experts who found the video Sanders shared was likely sped up. The effect makes Acostas hand movement appear more forceful than it actually was.

That is just dishonest reporting, Trump said of the suggestion the video had been altered. He added that Acosta may not have been overly horrible to the intern, but he was not nice.

The president threatened to revoke other reporters credentials, as well, if the press does not show more respect.

Trump, who called Acosta a rude, terrible person at the Wednesday press conference, bashed the CNN star once again on Friday on the White House lawn before adding journalist April Ryan to the mix. Trump called Ryan, a National Urban Radio Network correspondent, a loser who doesnt know what the hell shes doing.

Trump accused her of stirring up publicity in order to get a pay raise. On Wednesday, he forcefully ordered her to sit down after she stood to ask a question.

Its such a hostile media, Trump said at the time, telling Ryan she rudely interrupted a writer for the Daily Caller, a right-wing fringe website.

Trump also lashed out at CNNs Abby Phillip for asking whether his new acting attorney general, Matthew Whittaker, would rein in the special counsels Russia investigation.

What a stupid question that is, the president said. What a stupid question.

He added: But I watch you a lot. You ask a lot of stupid questions, then turned and walked away.
