Washington (CNN) – In a sign Congressional Republicans intend to keep political pressure on the administration over Benghazi, House Speaker John Boehner convened a meeting Thursday morning to discuss last year's attack on the U.S. consulate in Libya with key House committee chairmen and several GOP Senators who have been critical of the administration's handling of the incident.
Boehner told reporters at his weekly press conference that there are "some members who wanted to have a conversation, kinda compare notes on what we know and what we don't know and frankly there is a lot we still don't know, and so it was a friendly exchange of information and some decisions about a way forward."
The attack, which occurred on September 11, 2012, killed four Americans, including U.S. Ambassador to Libya Chris Stevens.
Pressed on what additional information Republicans on the Hill were seeking, Boehner said, "I think on what happened prior to September 11th, what actually happened on September 11th and then why it was described for weeks after as something that it wasn't, when the people who were watching this knew it was a terrorist attack."
A senior House GOP aide told CNN the purpose of the meeting was for committee leaders to "lay out what they know and figure out what questions still exist."
"What are they still looking for and what are they hearing from their members?" the aide added.
This aide said there are "some members who feel they don't have all the answers they want."
The issues outlined by Boehner were the subject of several congressional hearings at the end of 2012 and the beginning of this year that included testimony from then-Secretary of State Hillary Clinton.
Many Republicans, including Sen. John McCain and Sen. Lindsey Graham, were among those GOP members in the meeting with Boehner. They continue to say they're not satisfied with the answers provided in a report on the attack conducted by an independent review board, or with how top officials in the Obama administration reacted to the event.
The controversy over the lack of adequate security measures at the Libyan consulate and why the administration initially described the attack as a spontaneous demonstration–but then later acknowledged it was planned–has become a conservative cause célèbre. At a political conference last week outside Washington featuring speeches by top GOP party leaders, several speakers focused on the Benghazi issue and argued the president wasn't giving a full account of what happened.
Rep. Dutch Ruppersberger, the top Democrat on the House Intelligence Committee, wasn't in the meeting led by Boehner, but told CNN on Thursday that Congress was still gathering information and believed the administration was cooperating.
"The only thing there is an issue about whether or not certain people need to be subpoenaed. If members of Congress need to get more information, and there's a pushback, we have the ability to do that. But from what I understand, we're getting the information that people are talking to us," Ruppersberger said.
Sen. Dianne Feinstein, D-California, who chairs the Senate Intelligence panel told reporters Wednesday that her committee's own report was nearing completion, but was awaiting further input from Republican members.
"Our part of it is the intelligence. The majority has really, I think, knows what its findings are and are ready, and hopefully the minority shortly will have their additions and we'll able to get something out," Feinstein said.
