Jeb Bush is stepping down from his post at a health care firm at the end of the month, as he weighs a potential bid for president. 

Bush spokeswoman Kristy Campbell confirmed to Fox News that the former Florida governor will resign from Tenet Healthcare Corp.'s board on Dec. 31. The decision was first reported by The Wall Street Journal. 

Bush announced last week that he would "actively explore" a run for president in 2016.
