Update: Senate Majority Leader Harry Reid, D-Nev., filed paperwork Wednesday to force a vote on Chuck Hagel's nomination to be defense secretary.
Unless Republicans agree to take up the nomination sooner, the first procedural vote will come Friday. If Hagel passes the 60-vote threshold on that vote, he would receive a final vote Saturday.
WASHINGTON -- Senate Republican leaders are mounting a concerted push to delay Chuck Hagel's nomination beyond this week, and it looks like they're making headway.
Sen. Chuck Grassley, R-Iowa, said GOP leaders have been sounding out rank-and-file members on the issue. For his part, Grassley told them that he would support delaying Hagel's vote to get more information on the Sept. 11, 2012, attack on the U.S. Consulate in Benghazi that killed four Americans, including Ambassador Chris Stevens.
"Holding up the Hagel nomination to get that information is very legitimate," Grassley told reporters during his weekly conference call.
Grassley did not take a position on the nomination itself and said his comments did not mean that he would support a filibuster in the future.
Call it a filibuster, a "hold" or anything else, but Hagel needs at least five Republican votes to hit the magic number of 60 required to short-circuit such delaying tactics. Previously, it looked like he easily had the votes.
At least a half-dozen Senate Republicans have indicated they would support giving Hagel an up-or-down, simple majority vote, even if they ultimately opposed him.
One of those was Sen. Roy Blunt, R-Mo., a member of the Senate Armed Services Committee who voted against advancing his nomination Tuesday.
The committee, controlled by Democrats, overcame GOP opposition and sent the nomination to the floor on a party-line vote.
But Blunt told Missouri reporters Wednesday that he now would back an effort to delay the vote to get additional information from Hagel. Some senators are seeking additional personal financial information.
Blunt also noted that the Senate is on recess next week and a lot can happen in 10 days.
The White House has criticized linking Hagel's nomination to the Benghazi attack and said the Senate needs to move on the nomination.
Grassley said his main goal in holding up Hagel is to wring Benghazi answers from the administration, but he said the requests for additional financial information from Hagel are legitimate.
He said Hillary Clinton turned over a list of all contributors to her husband's foundation when she was nominated to be Secretary of State.
"So there's precedent for getting that information," he said.
Democrats have said the financial information requests go far beyond anything required of other nominees and insisted that Hagel not be held to a different standard.
