Republicans are taking aim at Nancy Pelosi over her accusation that the Central Intelligence Agency lied to Congress about harsh interrogation methods.

House Speaker Pelosi is accusing the CIA and Bush administration of not telling her and Congress about the use of waterboarding. She's standing by previous claims that she did not know the tactic was being used.

Pelosi Says CIA Lied To Congress

"Just to be clear, you are accusing the CIA of lying to you in September of 2002," a reporter asked Pelosi.

"Yes, they mislead the Congress of the United States," Pelosi answered. "I'm telling you that the talked about interrogations that they have done and said we want to use enhanced techniques and we have legal opinions that say that they are ok. 'We are not using waterboarding,' that is the only mention that they were not using it."

GOP Lawmakers: House Speaker Knew About 'Advanced Techniques'

Pelosi wants to investigate the Bush administration's use of waterboarding, but the CIA and Republican lawmakers say she knew it was being used all along.

"It's pretty clear that they were well aware of what these enhanced interrogation techniques were," said House Minority Leader Rep. John Boehner R-Ohio.  "They were well aware that they had been used, and it seems to me that they want to have it both ways."

"Boehner says Pelosi has offered several different explanations about her knowledge of the interrogation techniques.
