ABC’s Terry Moran anchors a special one-hour “Nightline” tonight titled “Nightline: Revolution Day.” This is the second one-hour “Nightline” on the subject of Egypt in the last 7 shows. Moran is in Cairo as is ABC’s Jim Sciutto. “This Week” host Christiane Amanpour will contribute from New York. Last Friday was the first night of a shortened “Nightline” as “Jimmy Kimmel Live” now starts at MidnightET. Tonight, Kimmel goes on at 12:30am.
