In another 2016 signal, Jeb Bush to step down from Barclays

Jeb Bush is stepping down from an advisory role with British banking giant Barclays.

A Bush spokesman said Thursday that the former Florida governor would resign his senior advisor position at the end of the year. Bush has been with the banking and financial services firm since 2009.

The move is another sign that Bush is moving toward a 2016 presidential bid. The likely Republican contender issued a statement this week that he's actively exploring a run.

Bush has yet to step away from a series of other business interests. He raised more than $60 million as chairman and manager of a new private equity fund as recently as September.

Opposition researchers in both parties are already sifting through the business activity seeking fodder for attack.
