Part II of Peter Doocy‘s “The Man Who Killed Usama Bin Laden” drew a preliminary 3.37 million viewers last night, topping even Part I on Tuesday night and making it the most-watched documentary on Fox News ever. Part II was up +25% in viewers and up +10% in the demo vs. Part I.

The special was the most-watched show on Fox News yesterday in both viewers and the A25-54 demo. In the special, Robert O’Neill, a former Navy SEAL, talked about his involvement in the mission to kill Usama bin Laden, and what speaking out about the secret operation has meant to him and his family.

O’Neill is not done talking. He was on “Happening Now” earlier today, on “The O’Reilly Factor” tonight and he’ll be interviewed by Savannah Guthrie tomorrow on “Today.”
