Former Nixon White House aide John Ehrlichman, above, who went to prison over the Watergate scandal, said he told writer Tom Clancy all he knows about the 1972 break-in and cover-up for a new documentary. The made-for-television project will include White House tapes that have never been heard before, Ehrlichman said. Clancy interviewed 25 key figures and studied documents in “John Ehrlichman: In the Eye of the Storm.” Ehrlichman, who co-wrote the film, said he and the producers are in negotiations with a TV network to air it later this year, but he wouldn’t name the network.
