WASHINGTON (AP) - Jeb Bush has resigned all of his board memberships - both nonprofit and business - in a move that signals growing interest in a 2016 presidential run.

WASHINGTON (AP) Jeb Bush has resigned all of his board memberships both nonprofit and business in a move that signals growing interest in a 2016 presidential run.

An aide says the former Florida governor stepped down from his remaining board memberships on Wednesday, the last day of the year. It's a continuation of a process that began in December when Bush announced plans to actively explore a White House bid.

Spokesman Kristi Campbell calls Bush's review of his business interests "a natural next step as he turns his focus to gauging whether there is support for a potential candidacy."

Bush is seen as an early favorite of the Republican establishment as the next presidential primary season begins.

He remains a partner in Jeb Bush and Associates, his business consulting company.
