The Republican Party's two most recent presidents are choosing to not throw their support a candidate in the 2016 election rather than back presumptive GOP nominee Donald Trump, according to a new report.
The Texas Tribune reported on Wednesday that President George H.W. Bush and his son President George W. Bush have opted not to endorse any candidate, even after Republican rivals Sen. Ted Cruz and Ohio Gov. John Kasich dropped out.
An aide for the younger Bush released a statement, revealing that Bush doesn't plan to participate at all during the rest of the election season. His father's spokesman said Bush 41 was retired from politics, adding, "He came out of retirement to do a few things for Jeb, but those were the exceptions that proved the rule."
Trump viciously attacked former Florida Gov. Jeb Bush when they were rivals in the campaign, and even took to criticizing Bush 43 on a number of issues including his mishandling of 9/11
"I lost hundreds of friends, the World Trade Center came down during the reign of George Bush," Trump said during a debate in February, insisting Bush failed to keep Americans safe.

When asked if Bush should have been impeached, Trump responded, "You do whatever you want, you call it whatever you want."
But the decision to remain neutral in the general election is unprecedented in recent years. The elder Bush endorsed the Republican nominee for office every year since he lost his re-election in 1992 and the younger former President Bush did the same for John McCain in 2008 and Mitt Romney in 2012.
The family might be able to keep from endorsing Trump this go-around, but it's pretty clear how they feel about the GOP's 2016 pick.
"In my experience, the strongest person usually isn't the loudest one in the room," George W. Bush said at a campaign stop in South Carolina.
