American race to White House: Both W.Bush senior and junior refuse to endorse Donald Trump .

President George H.W. Bush and his son President George W. Bush have no plans to endorse Donald Trump, their spokespeople told ‘ABC News’.

“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, former Florida governor and son and brother of the former presidents, left the race in February.

‘The Texas Tribune’ was the first to report the news.
