Former Florida Gov. Jeb Bush is edging toward a bid for the 2016 Republican presidential nomination, his son, George P. Bush said Sunday. In an appearance on ABC "This Week," the younger Bush said his father still is "assessing" the idea but it is looking more likely he will run.

"I think it's more than likely that he's giving this a serious thought and moving -- and moving forward," said George P. Bush, who added a run was less likely "a few years back."

Jeb Bush is the brother of former President George W. Bush and the son of former President George H.W. Bush. He decided against running in 2012 despite encouragement from Republicans but has been headlining fundraisers this election cycle for GOP candidates.

In an interview with the Associated Press, Jeb Bush has said his wife would support a presidential run and his parents are "neutral, trending in a different direction." His mother was quoted last year as saying there had been enough Bushes in the White House.

George P. Bush, who is running for the Texas land commission, said his family would back his father's run.
