Former Republican presidential candidate Jeb Bush apparently mocked President Trump’s relationship with his family during a speech at Yale University and was quickly corrected by two of the president’s sons.

Bush, the son of former President George H.W. Bush and brother of former President George W. Bush, said he returned home after the 2016 primary race in South Carolina to children “who actually love me” without mentioning Trump during a lecture Tuesday at Yale University.

The crowd responded with wild applause and many audience members told the Yale Daily News they understood the reference to Trump.

Two of Trump’s sons shot back at Bush on Twitter, with Donald Trump Jr. proclaiming his love for his father and taking a shot at the former GOP candidate.

“Jeb! I love everything about my father. I love that he’s a fighter, I love that he has guts, I love that he’s President (all those things you’re not)​,” Trump Jr. posted late Wednesday night on Twitter. “Also love that he learned enough about politics in a few weeks to dismantle you piece by piece despite it being your life’s work​.”​

Eric Trump also defended his father.

“@JebBush I actually love my father very much. #PleaseClap​,” he said.​

D​uring the Republican primary, Trump often rode Bush, who dropped out of the race after the South Carolina primary in February 2016, as “low-energy Jeb.” ​

Bush also joked that he didn’t want to speak about the primary race, saying “I’m still in therapy.”
