Bush 41, 43 Do Not Plan to Endorse Donald Trump

Trump is the last man standing in the GOP race.

"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.'"

The Texas Tribune was the first to report the news.
