George P. Bush told ABC's "This Week" that his father is "still assessing" a presidential bid, but suggested it was more likely that he would seek the White House this time. The ex-governor declined to run for president in 2012 despite encouragement from Republicans.

"I think it's more than likely that he's giving this a serious thought and moving — and moving forward," said the younger Bush, who is running for Texas land commissioner.

Asked if that meant it was "more than likely that he'll run," George P. Bush responded: "That he'll run. If you had asked me a few years back ... I would have said it was less likely."

Jeb Bush, the brother of former President George W. Bush and the son of former President George H.W. Bush, would stand out in what could be a crowded Republican field in 2016.

Bush has headlined fundraisers for Republican candidates and committees and helped campaigns for governor in Iowa, South Carolina and Nevada, three of the first four states to hold early presidential primaries.
