Newt Gingrich says Bushes acting ‘childishly’ and need to ‘get over’ Jeb’s loss

Newt Gingrich accused the Bush family of behaving “childishly” by skipping this week’s Republican National Convention and refusing to endorse Donald Trump.

The former speaker of the House, who was widely considered one of the top three vice presidential contenders for Trump, made the comments today on “Good Morning America” in Cleveland, where the convention kicks off.

“The reason people nominated Donald Trump is because they weren’t happy and, frankly, I think the Bushes are behaving childishly,” Gingrich told George Stephanopoulos on “GMA.” “Jeb lost. Get over it.”

Former President George H.W. Bush and his son former President George W. Bush have no plans to endorse Trump, their spokespeople told ABC News in May.

“President Bush does not plan to participate in or comment on the presidential campaign,” the younger Bush’s spokesman, Freddy Ford, said.

Jim McGrath, spokesman for the elder Bush, said the 41st president is out of politics.

“At age 91, President Bush is retired from politics,” McGrath said in an email. “He naturally did a few things to help Jeb, but those were the ‘exceptions that proved the rule.'”

Jeb Bush, a former Florida governor and son and brother of the former presidents, left the race in February.

It’s the first time in the last five election cycles that Bush 41 has not endorsed the GOP nominee.

The three Bushes aren’t the only no-shows at the Republican National Convention this week. Former nominees Mitt Romney and John McCain and even some convention speakers — House Speaker Paul Ryan and Sen. Ted Cruz, most prominently – won’t be attending. Former rival John Kasich, who also happens to be Ohio’s governor, will also be absent.
