Anthony Scaramucci sent his wife a text after she gave birth to their second child saying, "Congratulations, I’ll pray for our child," it has been claimed.
Donald Trump’s communications director reportedly sent the message after missing the birth of his second child, James, with his estranged wife Deidre.
The pair reportedly separated some months ago and Ms Scaramucci filed for divorce just two weeks before she gave birth to her son, when she was eight months pregnant.
Mr Scaramucci was in West Virginia alongside the US President when his wife went into labour, according to US gossip site Page Six.
But four days after his birth, the 53-year-old had yet to meet his newborn son.
A source close to the presidential aide said there had been talks between the couple so Mr Scaramucci could be present while his estranged wife gave birth – but the planning fell through.
He said: "There was discussion between him, her and the divorce attorneys about Anthony going to the hospital and unfortunately… the delivery was sudden."
Ms Scaramucci’s anger with her husband was reportedly a factor for the split. "She’s mad. They aren’t really speaking right now," the source said.
Another insider close to Mr Scaramucci claimed he was actually the victim of his wife’s verbal abuse: "She would say, ‘You’re a grifter, you’re this.’ She would mock him for being a Trump sycophant."
It comes just days after Mr Scaramucci criticised his new colleagues in a foul-mouthed tirade to a reporter from The New Yorker.
He called Reince Priebus, the White House chief of staff who resigned on Friday, "a f***ing paranoid schizophrenic".
Mr Scaramucci also said he was not like Steve Bannon, Mr Trump’s chief strategist, because "I’m not trying to suck my own c***".
