WASHINGTON (CBSDC/AP) — The chairman of the Senate Intelligence Committee hammered House Republicans over the Benghazi Select Committee.

Speaking to CNN on Sunday, Sen. Dianne Feinstein, D-Calif., called the House investigation into the Sept. 11, 2012 attack at the U.S. consulate in Benghazi that left U.S. Ambassador Chris Stevens and three other Americans dead “ridiculous.”

“I think it’s a hunting mission for a lynch mob, actually. I think that’s what’s going on,” Feinstein told CNN. “There have been four major reports. We spent a year-and-a-half on a report. We held hearings. Thousands of pages reviewed.”

Feinstein compared the Benghazi incident to the 1983 bombing at a U.S. Marine compound in Beirut that killed 241 U.S. service personnel.

“If you compare it to Ronald Reagan, who was a big Republican hero, and what happened in Beirut with three attacks, with 240 servicemen, with seven CIA officers, with one chief of station being tortured to death, and Reagan admitted we weren’t ready for it,” Feinstein told CNN. “Well, since then, a lot of things have been done. There were faults. The intelligence was there. Action should have been taken.”

Feinstein added that she believes all the questions have been answered as to the response by the Obama administration.

“Our report was bipartisan. And they were certainly answered to the satisfaction of the Intelligence Committee,” she told CNN.

The Obama administration and House Democrats are undecided about whether to take part in or boycott the investigation.

House Speaker John Boehner created a select committee to examine the response to the deadly assault on the U.S. diplomatic post in Libya. Rep. Trey Gowdy, R-S.C., will head the investigation.

Boehner and other Republicans accuse the administration of misleading the American people after the attack to protect Obama in the final weeks of his re-election campaign, and of stonewalling congressional investigators ever since.
