Former US President George HW Bush has planned to vote for Democratic presidential nominee Hillary Clinton in the upcoming November 8 elections,a media report said.

The news was revealed on Monday by Kathleen Hartington Kennedy Townsend, the former Maryland lieutenant governor and daughter of the late Robert F Kennedy, a Democrat and brother of slain President John F Kennedy, Politico reported.

Townsend posted a picture on her Facebook page next to the 92-year-old former president with the caption: "The President told me he’s voting for Hillary!!"

In a telephone interview, Townsend said she met with Bush in Maine earlier on Monday, where she said he made his preference known that he was voting for a Democrat.

"That’s what he said," she told Politico.

George H.W. Bush, who served from 1989 to 1993 and also as Vice President from 1981 to 1989, and former First Lady Barbara Bush have stayed out of the political debate since campaigning earlier this year for their son Jeb’s unsuccessful bid for president.

Neither George H.W. Bush nor his son, former President George W. Bush, attended the Republican National Convention held in July in Cleveland where Trump accepted the nomination.
