Jeb Bush, son to one former US president and brother to another, has thrown his hat into the ring for the 2016 race, announcing he had consulted his family and decided to explore a bid.
"As a result of these conversations and thoughtful consideration of the kind of strong leadership I think America needs, I have decided to actively explore the possibility of running for president," he said on Tuesday.
The 61-year-old former Florida governor is the first serious Republican contender to announce a possible run in his party's primaries.

Bush is a mainstream Republican seen as less ideologically rigid than the conservatives considering a presidential run, like Senators Ted Cruz and Rand Paul.
"I have no clue if I'd be a good candidate. I hope I would be," Bush told ABC television affiliate WPLG-TV on Sunday.
In October, George W. Bush said his younger brother "wants to be president" and that he was "pushing for him to run".
