Did last week's climate change negotiations drive Democratic congressman Henry Waxman to exhaustion? After feeling ill on Tuesday, the Chairman of the House Energy and Commerce Committee fainted in his D.C. office. He was later admitted to the hospital in his home state of California, for routine testing. The episode came fresh on the heels of last week's historic climate change legislation, which Waxman, 69, steered through a close vote in the House. He remained in the hospital on Wednesday, but he is feeling better and "is in good spirits," his office said.
