As former Florida Gov. Jeb Bush explores running for president, he has resigned from the board of directors of Jacksonville-based Rayonier Inc., according to a filing with the U.S. Securities and Exchange Commission.

Bush’s resignation, submitted last week, is effective Wednesday. Bush has been one of two high-profile political figures on the board of the timber and real-estate company, along with former U.S. Sen. Blanche Lincoln of Arkansas, according to information on Rayonier’s website.

Also last week, Bush submitted his resignation, effective Wednesday, from the board of Dallas-based Tenet Healthcare Corp. Among the remaining members of the Tenet board is former U.S. Sen. Bob Kerrey of Nebraska. Rayonier and Tenet said in SEC filings that Bush did not have disagreements with the companies.

Bush announced this month that he would “actively explore” a possible bid for president in 2016.
