WASHINGTON (AP) - House Republicans on Thursday passed a measure opening a new investigation of the deadly assault in Benghazi, Libya, vowing to dig deeper in a search for truth.
Democrats declared it a political ploy to raise campaign cash and motivate voters.
The House voted 232-186 to establish the panel that Speaker John Boehner hopes will answer questions that linger almost 20 months after the Sept. 11, 2012, attack on the U.S. diplomatic mission. Seven Democrats, many facing tough re-election campaigns, broke ranks and joined Republicans in supporting the probe.
All local members of Congress voted to open the investigation.
The panel's investigation will be the eighth on Benghazi and will examine the entirety of the attack that killed Ambassador Chris Stevens and three other Americans. Independent, bipartisan and GOP-led probes have faulted the State Department for inadequate security at the outpost, leading to four demotions. No attacker has yet been brought to justice.
Republicans say they're unsatisfied with explanations so far, and they have leveled a range of accusations against President Barack Obama, former Secretary of State Hillary Rodham Clinton and other senior administration officials. Chief among them: that the administration misled the American people about the nature of the attack during a presidential election campaign and stonewalled congressional investigators.
"We will not take any shortcuts to the truth, accountability or justice," Boehner said during House debate.
Democrats remain divided over whether to boycott the select committee. They are concerned that their participation would grant legitimacy to what they believe will be a partisan forum. But they also worry that if they avoid it they won't have the chance to counter GOP claims and defend potential witnesses - including Clinton, a possible 2016 presidential candidate.
Party leaders will meet with their rank and file this morning to decide on the next step.
Republican Rep. Ileana Ros-Lehtinen of Florida criticized the "song and dance" she said came from Clinton when House members wanted to question her about Benghazi a few months after the attack. Clinton's testimony before the House Foreign Affairs Committee was delayed when she missed a month of work toward the end of her tenure after suffering a virus, then a fall and a concussion, and then brief hospitalization for a blood clot near her brain.
Rep. Louise Slaughter, D-N.Y., said no evidence uncovered in any of the investigations thus far suggests wrongdoing by the administration. Republican claims have descended into "the crass and unbelievable," she said.
Rep. Adam Schiff, D-Calif., said the questions "have been asked and answered time and time and time again ... Let's end the political circus."
Benghazi has produced 13 public hearings, the release of 25,000 pages of documents and 50 separate briefings. The select committee won't be the only inquiry, as other GOP-led congressional panels continue their probes, including a House Oversight investigation which just last week took the extraordinary step of subpoenaing a Cabinet member. Secretary of State John Kerry hasn't said when he might testify.
Democrats deride the effort as a conservative campaign designed to energize Republican voters in typically low-turnout midterm elections.
Boehner's legislation creates a select House committee through the end of the year. It will have to be reapproved when a new Congress begins in January or go out of existence. The select committee has no explicit financial constraints.
Earlier this week, the National Republican Congressional Committee sent an email vowing that "no one will get away" from the committee's investigation and asking people for donations.
Rep. Steve Israel of New York, the Democrat campaign committee chairman, called fundraising off Benghazi "despicable and insulting."
