Former Florida Governor Jeb Bush has resigned from all nonprofit and corporate boards as he explores a presidential campaign, the Washington Post reported Wednesday.

The Republican has stepped down from his own education foundation and is no longer a paid adviser to Academic Partnerships, a for-profit education company, according to the newspaperHe has also parted ways with Empower Software Solutions and CorMatrix Cardiovascular Inc., according to the Associated Press.

“Bush was reviewing other businesses in which he is principal partner or owner,” the Post reported, citing an aide. They include consulting firm Jeb Bush & Associates and business advisory group Britton Hill Partnership.

Bush spokeswoman Kristy Campbell did not immediately respond to a request for comment on Thursday.

Bush's business interests and ties to corporate boards would be scrutinized by opponents and the media during a presidential campaign if he runs. He invited comparisons to the party's 2012 nominee, former Massachusetts Governor Mitt Romney, by expanding his private equity portfolio this year, including a new fund in November, BH Global Aviation, that raised $61 million in September, mostly from foreign investors.

Earlier this week, company documents showed Bush would resign as director of Rayonier Inc., a Jacksonville, Fla.-based timber company where he had been a director since 2008. He was also set to leave his paid advisory role with at Barclays, a London-based investment bank that has cut thousands of jobs and been fined for interest-rate manipulation.
