President George W. Bush is taking powerful anti-depressant drugs to control his erratic behavior, depression and paranoia, Capitol Hill Blue has learned. The prescription drugs, administered by Col. Richard J. Tubb, the White House physician, can impair the President's mental faculties and decrease both his physical capabilities and his ability to respond to a crisis, administration aides admit privately. "It's a double-edged sword," says one aide. "We can't have him flying off the handle at the slightest provocation but we also need a President who is alert mentally."Tubb prescribed the anti-depressants after a clearly-upset Bush stormed off stage on July 8, refusing to answer reporters' questions about his relationship with indicted Enron executive Kenneth J. Lay. "Keep those motherfuckers away from me," he screamed at an aide backstage. "If you can't, I'll find someone who can." [more] and [more]
