HOUSE AND HIS TEAM BATTLE TO SAVE A PRESIDENTIAL HOPEFUL, AND HOUSE REFUSES TO GIVE IN TO VOGLER'S ULTIMATUM WHEN GIVEN THE CHANCE TO SAVE ONE OF HIS TEAM MEMBERS ON "HOUSE" TUESDAY, AUGUST 9, ON FOX

Chi McBride and Joe Morton Guest-Star

At a high-level campaign fundraiser, up-and-coming Senator Tom Wright (guest star Joe Morton) becomes violently ill. Vogler (guest star Chi McBride) pushes House to take Wright's case and also dangles a new incentive in front of him: deliver a speech on behalf of Vogler's pharmaceutical company, and save his whole team. While the Senator's symptoms and tests point to AIDS, a condition which would squash his White House dreams forever, House and the team dig for different answers. Meanwhile, House gives the speech, but it's not exactly what Vogler had in mind in the "Role Model" episode of HOUSE Tuesday, Aug. 9 (9:00-10:00 PM ET/PT) on FOX. (HOU-117) (TV-TBA)
