US President Donald J. Trump announces his nominee to replace retiring Supreme Court Justice Anthony Kennedy, Washington, USA - 09 Jul 2018

By many accounts, including his own, PresidentDonald Trumpdoes not like it when grown men cry.

“He’d rather see a man keel over from a heart attack, trying to restrain himself, than bawling in front of the nation,” Trump biographer Michael D’Antonio, author ofThe Truth About Trump,tells PEOPLE. “He is just not a person who tolerates displays of emotion like this.”

As Trump’s Supreme Court nominee Brett Kavanaugh, 53,broke down in tears on Thursdayduring his Senate testimony while defending himself against allegations of sexual assault, others with a pulse on the president’s anti-crying views agree it didn’t go over well.

Omarosa Manigault-Newman— a former senior aide who has known Trump, 72, for well over a decade —tweeted Thursday: “I wonder how #45 is reacting to Kavanaugh’s crying. The former #45 hates for men to show any sign of weakness.”

Vanity Fair‘s Gabriel Shermantweeted that Kavanaugh’s “cryinghas unnerved some White House aides, source says. ‘People don’t know why he is crying.'”

Regarding Kavanaugh’s sniffling Thursday, “Trump is going to be appalled initially — this is not his idea of masculinity,” D’Antonio says. “He is a 1950s boy, don’t-cry, punch-them-in-the-nose kind of guy.”

“Judge Kavanaugh showed America exactly why I nominated him. His testimony was powerful, honest, and riveting.”

Donald Trump, Jr. chimed in,tweeting“I love Kavanaugh’s tone” as he fought for his honor.

D’Antonio surmises President Trump will be happy if Kavanaugh gets through the Senate confirmation process, with a first vote expected Friday.

“But if he doesn’t get through,” D’Antonio says, “he will chalk it up to the man being a loser.”
