In another 2016 signal, Jeb Bush to step down from Tenet Healthcare Corp. board

Jeb Bush is stepping down from the board of directors of Tenet Healthcare Corp.

The health care company said in a regulatory filing Wednesday that the former Florida governor would resign his seat at the end of the year. Bush has been a director since 2007.

Tenet noted that Bush is "not resigning on account of any disagreement" with the company.

The move comes as Bush actively explores a presidential run and unwinds some of his business commitments. A spokesman said last week that the potential Republican contender will leave his advisory role with British banking giant Barclays by Dec. 31.

According to corporate filings, Bush still sits on the boards of three other companies and is chairman and manager of a Florida-based private equity and business advisory group.
