Someone important appears not to be telling the truth about her knowledge of the CIA's use of enhanced interrogation techniques (EITs). That someone is Speaker of the House Nancy Pelosi. The political persecution of Bush administration officials she has been pushing may now ensnare her.

Here's what we know. On Sept. 4, 2002, less than a year after 9/11, the CIA briefed Rep. Porter Goss, then House Intelligence Committee chairman, and Mrs. Pelosi, then the committee's ranking Democrat, on EITs including waterboarding. They were the first members of Congress to be informed.

In December 2007, Mrs. Pelosi admitted that she attended the briefing, but she wouldn't comment for the record about precisely what she was told. At the time the Washington Post spoke with a "congressional source familiar with Pelosi's position on the matter" and summarized that person's comments this way: "The source said Pelosi recalls that techniques described by the CIA were still in the planning stage -- they had been designed and cleared with agency lawyers but not yet put in practice -- and acknowledged that Pelosi did not raise objections at the time."

When questions were raised last month about these statements, Mrs. Pelosi insisted at a news conference that "We were not -- I repeat -- were not told that waterboarding or any of these other enhanced interrogation methods were used." Mrs. Pelosi also claimed that the CIA "did not tell us they were using that, flat out. And any, any contention to the contrary is simply not true." She had earlier said on TV, "I can say flat-out, they never told us that these enhanced interrogations were being used."

The Obama administration's CIA director, Leon Panetta, and Mr. Goss have both disputed Mrs. Pelosi's account.
