Doctor Tomorrow (1997) #4

Doctor Tomorrow is dragged into the 1950s kicking and screaming! Despite Doc's heroic efforts in Korea and commie busting back in the states, "Tailgunner" Joe McCarthy sets his sights to expose Doc as a dyed-in-the-wool Communist. Besieged on all sides, Tomorrow is then betrayed by one of his closest allies, threatening his future technology and even his life!
