"If there is going to be a true bipartisan inquiry, we'll participate," Rep. Steve Israel, D-N.Y., told reporters following the meeting. "If it's engineered to be a Republican campaign strategy, it's much harder for us to participate."
Four Americans, including U.S. Ambassador Chris Stevens, were killed when militants stormed the diplomatic outpost. Republicans, who insist the Obama administration hasn't come clean on what happened, voted Thursday to create the special committee.
House Democrats have issued several demands if they are to participate in the select committee. Rebuffed on their request for an equal split in membership, Democrats are seeking guarantees they'll have equal access to documents, say on subpoenas and the right to question witnesses. Staff level negotiations have continued.
Israel said that House Minority Leader Nancy Pelosi, D-Calif., had made several calls to Boehner on Thursday that went unanswered.
Rep. Gerry Connolly, D-Va., said the sentiment in the caucus was shifting away from a boycott in favor of participating, but Democrats wanted to know the "rules of engagement" first. 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.
Rep. Rosa DeLauro, D-Conn., floated the idea of token participation with just one Democrat, but Connolly said he didn't support that step.
A member of the Democratic leadership, Rep. Jim Clyburn of South Carolina, expressed his concerns about participating, saying, "if you're going to have a hanging don't ask me to bring the noose."
The panel's investigation means high-profile hearings in the months leading up to the elections, with Republicans grilling current and former Obama administration officials. Certain to be called to testify is former Secretary of State Hillary Rodham Clinton, the Democrats' potential 2016 presidential candidate.
Rep. Trey Gowdy, R-S.C., the former prosecutor tapped by Boehner to head the committee, said Friday he was unsure how quickly the committee could be established, but he has already begun planning.
"I've already started assembling and have been assembling a list of questions and kind of my own to-do list," Gowdy said in an interview.
The number of items on the list: "I'd probably say north of 100," Gowdy said.
Boehner maintains that the process will not be partisan, but Democrats have their doubts.
"This is 100 percent pure politics," Rep. Debbie Wasserman Schultz of Florida, chair of the Democratic National Committee, said Friday. She charged that Republicans are exploiting the families of the four victims of the Benghazi attack by keeping the issue alive.
Wasserman Schultz accused Republicans of doing all in their power "to keep this in the news," saying the GOP is returning its focus to Benghazi now because its staunch opposition to the Affordable Care Act "has lost its luster."
Boehner's legislation creates the special 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. The speaker was expected to announce the Republican members on Friday.
In the 20 months since the attack, multiple independent, bipartisan and GOP-led probes already have faulted the State Department for inadequate security at the outpost, leading to four demotions. No attacker has yet been brought to justice.
