WASHINGTON — The creation of a special committee to investigate the 2012 Benghazi attacks carries the potential for political gains — and risks — for Republicans.

The House of Representatives voted Thursday create a special panel to investigate the Sept. 11, 2012, attacks, a vote pushed through by the Republican majority on a largely party-line vote.

The panel is to investigate “all policies, decisions, and activities” dealing with the attack on the U.S. diplomatic mission in Benghazi that left four Americans dead. Its timetable is open-ended — virtually assuring that hearings will be held, and reports will be issued, as the 2016 presidential campaign unfolds.

Friday, House Speaker John Boehner, R-Ohio, named six Republicans to join Chairman Trey Gowdy, R-S.C., on the committee: Reps. Jim Jordan of Ohio, Lynn Westmoreland of Georgia, Mike Pompeo of Kansas, Martha Roby of Alabama, Peter Roskam of Illinois and Susan Brooks of Indiana.

Democrats are torn about whether to participate. Minority Leader Nancy Pelosi, D-Calif., said Friday that “this is a stunt,” and she wanted to talk to Boehner before deciding whether, or whom, to name. She also said the families of two of the Benghazi victims had called and said, “Please don’t take us down this path again.”

Republicans, who will rule the committee 7-5, sense potential for staggering President Barack Obama and, perhaps more important, former Secretary of State Hillary Clinton on her way to the 2016 presidential race. They see fundraising possibilities, as well as a powerful tool for firing up their base for this midterm election, a time when turnout is traditionally low.

Many Republicans also worry they’re playing with political fire.

“The people who are seen as politicizing this are going to get burned” regardless of political party, warned Sen. Lindsey Graham, R-S.C.

Democrats have their own quandary. If they keep saying it’s all politics, they could look like they’re trying to avoid further examination of how the Obama administration responded to the attacks that killed four Americans including the U.S. ambassador to Libya.

“If Democrats are seen as not wanting to know more about Benghazi, if they’re seen as protecting the White House and Clinton, they’ll get burned,” Graham said.

Democrats seem unworried by that prospect. “Trying to politicize a tragedy where people lost their lives is not going to work out,” said Sen. Tim Kaine, D-Va., who last week endorsed Clinton for president in 2016.

Since the attacks on the U.S. special mission and nearby CIA annex in Benghazi, Republicans have questioned U.S. security arrangements and the military response to the incident.

Republicans see an opening for embarrassing Clinton, but polling suggests the public is not that interested. And a Pew Research Center survey last year, as Congress held hearings on Benghazi, found one-third of independents thought Republicans had gone too far.

While Republicans tend to follow Benghazi developments, independents and Democrats have been less engaged. When Congress held hearings on the incident a year ago, Pew found that 23 percent of Americans followed the hearings very closely — far behind the 40 percent who were following news about the economy and the rescue of three Cleveland women who had been held captive.

There’s also scant evidence yet that the incident will make much difference if Clinton runs for president. A March Pew poll found two-thirds of Americans approved of the job she did as secretary of state.

The Boehner appointees include Republicans who’ve been outspoken critics of the Obama administration. Pompeo and Westmoreland have been active on the House Intelligence Committee, asking sharp questions about the Benghazi incident.

Jordan has long been known at the Capitol as a vocal, brash White House critic. After Obama gave his State of the Union address in January, Jordan combined Benghazi with other matters and blasted the president.

Roby has been active in probing the military response to the incident. Roskam is a chief deputy whip and is considered close to Boehner. Brooks, a freshman who defeated a tea party-backed candidate Tuesday in the Republican primary, is a former federal prosecutor.

Pelosi had pressed for a committee evenly divided between the parties. Republicans noted that ratios that reflect the overall makeup of Congress are common. Republicans control 233 House seats to Democrats’ 199, and committees are usually divided according to that ratio. An exception is the Ethics Committee, which is split equally.

Special committees have been subject to majority rule. In 2007, when Pelosi, then the House speaker, pushed to create a special panel to study energy independence and global warming, it had nine Democrats and six Republicans. As soon as Republicans got control of the House in 2011, they abolished the panel.

Pelosi said Friday that she’d been trying to discuss the committee with Boehner. They spoke briefly in the chamber before the House left Friday for a weeklong recess. No further meetings are scheduled.

Pelosi sent Boehner a letter Friday that said the Republican rules for the committee were “fundamentally unfair.” She asked that Democrats have “a real voice on the committee” over the issuing of subpoenas, how witnesses would be questioned and deposed, and “the specific protocols governing how documents and other information would be obtained, used and potentially released by the committee.”

While the majority traditionally controls the committee process, cooperation with the minority isn’t unusual.

In response, Boehner spokesman Michael Steel said: “We made a fair offer. We hope they appoint members. At this point, it’s time to get to work.“

Asked on Friday whether the White House would cooperate with the new committee, spokesman Eric Schultz said, “We cooperate with all legitimate oversight requests,” but he noted that the “true motive” of the panel may have been that the Republicans are fundraising over it.

Surveys show that while Republicans tend to follow Benghazi developments, independents and Democrats have been less engaged. When Congress held hearings on the incident a year ago, Pew found that 23 percent of Americans followed the hearings very closely — far behind the 40 percent who were following news about the economy and the rescue of three Cleveland women who had been held captive.

When Pew asked people to cite the most negative thing about Clinton, Benghazi topped the list, but at just 15 percent. Gallup asked a similar question — what would be the worst or most negative thing about a Clinton presidency — and Benghazi was seventh on the list, at 2 percent. Tops was that she was not qualified, followed by her gender.

Benghazi could matter politically, though, because it motivates Republicans, said Carroll Doherty, Pew director of political research.

The party is trying to show Benghazi is part of a pattern typical of Clinton’s tenure as secretary of state from 2009 to 2013. If she runs, “both in the primary and general she’ll be facing people with almost no foreign policy experience,” said Dan Holler, spokesman for Heritage Action, a conservative political group. “She’ll no doubt try to exploit that.”

If she does, Holler said, Republicans will contend Benghazi “does contribute to a narrative that she was a major player in a foreign policy agenda that is widely seen as a failure.”

“Benghazi is an issue for Hillary Clinton because she was the boss and it’s been handled very poorly from the very beginning,” said Kirsten Kukowski, Republican National Committee spokeswoman.

The National Republican Congressional Committee has been blogging regularly about the new committee, urging donors to “help fight liberals by donating today.”

Democrats, and some Republicans, are furious. “Fundraising off the Benghazi tragedy is despicable and insulting and has no place in the national conversation,” said Rep. Steve Israel of New York, the Democratic Congressional Campaign Committee chairman.

The Benghazi committee chairman was also unhappy. “Certain things … ought to be above politics, like the murder of our four fellow Americans, and like whether you can trust what any administration, Republican or Democrat, tells you in the aftermath of a tragedy,” Gowdy told MSNBC. “That, to me, transcends politics.”

But Boehner won’t tell Republicans to stop. Asked three times at his weekly news conference Thursday whether such appeals were appropriate, he would not answer the question, instead giving roughly the same answer three times: “Our focus is on getting the answers to those families who lost their loved ones, period.”

Be careful, said Democrats and some Republicans. Legitimate questions are being raised, they say. Don’t cheapen the investigation.

“This story is not going away until you can give a coherent answer,” said Graham. “Remember, Republicans are doing well without Benghazi this year, and just being quiet about it is probably smart.

“But ask yourself this: What do we tell the families?” he asked.
