Washington (CNN) - Sen. John McCain - who has the ability to make or break the Hagel nomination - told CNN Thursday he had not received a White House letter with new information on the Benghazi attacks, exacerbating the partisan wrangling ahead of a looming Senate vote on cabinet nominee Chuck Hagel Friday.
A trio of Republican senators - McCain, Kelly Ayotte and Lindsey Graham - have said they would hold up the Senate vote on Hagel until the White House answered questions about President Obama's communications with the Libyan government the night of the Benghazi attack.
Late Wednesday, the White House sent a response to that question to Sen. Carl Levin, the chairman of the Armed Services Committee. But as of Thursday morning, McCain said he had not seen that response and could not say how he would vote on Hagel. "I have not received the letter," McCain said Thursday. "They sent the letter to Sen. Levin. It was Sen Graham and I and Ayotte that asked for an answer. We haven't received an answer."
Before seeing the letter, McCain would not say whether he would support or oppose a move Friday to end a filibuster of Hagel's nomination. Democrats say right now they do not have the 60 votes to overcome a filibuster. That could change if McCain is swayed by this letter. "I have to receive a letter, I have to receive a letter, see whether I receive a letter or not, and there are other questions that other senators have raised which are not answered as well," McCain said.
