Pierce Bush, the grandson of the late President George H.W. Bush, is expected to announce a run for the U.S. Congress this morning. Bush is one of several Republicans running for the 22nd District in Texas, the seat southwest of Houston that's held by the retiring Pete Olson. Bush had reportedly been considering a bid for the nearby 7th District in west Houston, a seat his grandfather once held. Pierce Bush is an executive with the nonprofit Big Brothers Big Sisters Lone Star.
