NBC -- Obama, who was interviewed from the Map Room of the White House during the run-up to Sunday’s Super Bowl, was unabashed about using the game for his own purposes. After the interview, he joined 15 key members of Congress whom he invited to watch the game with him — seven of them from Pennsylvania or Arizona, home states of the Pittsburgh Steelers and the Arizona Cardinals. His goal was to build bipartisan support for his $825 billion-plus economic stimulus plan, which passed the House last week without a single Republican vote.
