As often happens, someone else says it better than I could.

Sorry, but this simply won't fly. Rockefeller doesn't learn about intelligence from the White House or from press releases -- he's the ranking member of the Senate committee on intelligence. He sees the same raw data that the President gets, and he has access to the same analysts that confer with the White House. The SSCI had ample opportunity for years to question the intel provided to them by the entire range of intelligence agencies regarding Iraq, and most of that well before the Bush administration took office.

Rockefeller cannot say with any degree of honesty that the White House misled him on the nature of the intelligence, unless he wants to claim that Bush stole his capacity for independent thought. Rockefeller saw the same data and reached the same conclusions as the White House. Now that the intel has been proven faulty, he wants to escape responsibility for it by turning the intel failure into a partisan smear campaign.
