In the case of House Speaker Nancy Pelosi, a leading supporter of the waterboarding Inquisition, it's because she's an idiot:

House Speaker Nancy Pelosi has backed down slightly in her fight with the CIA, saying that she really meant only to criticize the Bush administration rather than career officials.

'My criticism of the manner in which the Bush Administration did not appropriately inform Congress is separate from my respect for those in the intelligence community who work to keep our country safe,' Pelosi said in a statement.
 

Really? Are you sure Nancy? Let's look at the transcript from your earlier meltdown news conference:

QUESTION: Madam Speaker, just to be clear, you're accusing the CIA of lying to you in September of 2002?

PELOSI: Yes, misleading the Congress of the United States, misleading the Congress of the United States. I am.

Pelosi. Petard. No assembly required.
