WASHINGTON – Lawmakers said Sunday they want to know who had a hand in creating the Obama administration’s now-discredited “talking points” about the Sept. 11 attack on a U.S. diplomatic post in Benghazi, Libya, and why a final draft omitted the CIA’s early conclusion that terrorists were involved.

The answers could explain why President Barack Obama and top aides, including U.N. Ambassador Susan Rice, described the attack for days afterward as a protest against an anti-Islam video that spontaneously turned violent and why they played down any potential link to al-Qaida, despite evidence to the contrary.

Administration officials have defended the portrayal of the attack as relying on the best information available at the time that didn’t compromise classified intelligence.
