President Trump called Donald Jr. 'a f--kup' after he released emails about controversial meet with Russian lawyer, book says

President Trump blasted his firstborn son as a “f--kup” after learning he had released emails about a controversial Trump Tower meeting attended by a Kremlin-connected lawyer who had promised dirt on Hillary Clinton, according to Omarosa Manigault Newman’s forthcoming book.

Manigault Newman, who was unceremoniously fired from the White House last December, says the President erupted in anger after she met with him last July and told him she was “sorry to hear” Donald Trump Jr. had posted screengrabs on Twitter of his email exchanges with British publicist Rob Goldstone.

“He is such a f--kup,” Trump said of his son, according to Manigault Newman’s tell-all book, a copy of which was obtained by the Daily News. “He screwed up again, but this time, he’s screwing us all, big-time!”

A White House spokeswoman did not immediately return to a request for comment. A spokesman for Trump Jr. did not immediately respond to emailed questions.

Manigault Newman’s book, “Unhinged: An Insider’s Account of the Trump White House,” is set to hit the shelves Tuesday, but has already made national headlines and paints the President as an ignorant narcissist who routinely spews racially-charged and sexist language.

The infamous June 9, 2016 Trump Tower meeting, which is of interest to special counsel Robert Mueller, has caused repeated headaches for the President.

The Trump campaign first insisted the meeting was about adoptions of Russian children by Americans, but the President himself backpedaled on that claim earlier this month, tweeting the sit-down was hosted by his son “to get information on an opponent.”

“Totally legal and done all the time in politics — and it went nowhere,” Trump tweeted on Aug. 5. “I did not know about it.”

The Russian lawyer who attended the meeting, Natalia Veselnitskaya, has been tied to senior Kremlin officials. Emails obtained and released by Russian opposition group the Dossier Center show Veselnitskaya has been involved in the Kremlin’s efforts to overturn U.S. sanctions and extract information about anti-Kremlin activists.

Ahead of the Trump Tower meeting, Goldstone emailed Trump Jr. that Veselnitskaya had “official documents and information that would incriminate Hillary and her dealings with Russia and would be very useful to your father.”

Trump Jr. has maintained nothing came of the meeting, which was also attended by ex-Trump campaign chairman Paul Manafort and the President’s son-in-law, Jared Kushner.

Mueller is looking into the sit-down as part of his investigation into possible collusion between Trump’s campaign and the Russian government, according to sources.
