Jeb Bush may have been been humiliated by Donald Trump during the 2016 campaign, but the Republican former presidential candidate was not afraid to take a jab at the president this week.

Bush’s comments came during a discussion of the 2016 South Carolina GOP primary, which Trump won.

Bush — the younger brother of former President George W. Bush — also joked that he still reflects on his experience running for president in 2016, though he did not give any details.

“I’m not going to talk about the 2016 election,” Bush said, according to the Yale Daily News. “I’m still in therapy.”

Bush also stressed the need for more civil political discourse.

“If there was ever need for a Bill Buckley-like approach to transforming conservatism in this country, it is right now,” Bush said, referring to the conservative author and commentator who founded National Review magazine. “Maybe not a 19th-century or a 20th-century version of conservatism, but certainly a 21st-century version of that. And sadly, the fracturing of the conservative movement could not come at a worse time.”

“The 21st-century conservative agenda cannot be nostalgic about the past,” Bush added, calling for the spread of technology, greater globalization and more competition.

Bush was considered to be a front-runner to become the Republican nominee for president when he first announced his candidacy in 2015. However, he was among about 15 Republican candidates to lose to Trump.

Both Trump’s sons responded to Bush’s comments via Twitter.

“.@JebBush I actually love my father very much. #PleaseClap,” said Eric Trump, referencing a moment during the 2016 campaign when Bush begged a crowd he was addressing to applaud after he had finished a long statement.

Donald Trump Jr. also fired back at the veteran politician.

“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),” wrote Donald Jr. “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.”
