Jeb Bush slammed Republicans Saturday for giving President Trump a free pass on Russia — while blasting President Obama for the same thing.

“If your opponent does things that … your head explodes on … then when your guy does the same thing, have the same passion to be critical,” the former Florida governor fumed at Ozy Fest, a Central Park festival hosted by the digital news magazine Ozy.

Jeb’s jab appeared to be a thinly veiled reference to GOP leadership going easy on Trump for not criticizing Russia for its alleged meddling in U.S. elections. Trump has deflected criticism to Obama, questioning why his predecessor did not publicly disclose concerns about Russian hacking after the CIA first alerted him. Obama has said he confronted Russian President Vladimir Putin in a private meeting.

Bush, speaking on a panel alongside comedian Samantha Bee and entrepreneur Mark Cuban, implored Washington’s elected to “be civil.”

“Now, strength is measured by how you insult people,” the disgusted ex-presidential candidate told the crowd. “Reject it, because we’re never going to solve problems that way.”
