WASHINGTON (CNN) -- Sen. Carl Levin on Wednesday took a colleague's name off a statement issued Tuesday after his fellow senator said he hadn't seen the statement before it was released.

The initial statement, originally carrying the names of Levin, the chairman of the Senate's Armed Services Committee, and the committee's ranking GOP member, Sen. John McCain, slammed the administration for not specifying meaningful consequences for Iraqis if they don't meet their commitments.

The statement came in response to a letter from Secretary of State Condoleezza Rice that was itself a response to earlier letters from Levin and McCain.

McCain, who is introducing a resolution backing President Bush's plan to send more troops to Iraq, said Wednesday he hadn't seen the statement before it was released.

"We wanted to know what the benchmarks were that the president referred to in his speech" on Jan. 10, the Arizona Republican said. "We thought we ought to have those, OK? Now I'd like to analyze them, see which have been met, see which ones haven't been, and basically see how that bounces off our resolution, which has benchmarks as well."

Rice's letter attached a list of goals with a timeline dating back to September 2006 that the Iraqi Policy Committee passed. She also noted that Iraqi Prime Minister Nuri al-Maliki made a number of additional commitments, listing four of them but providing mo timeline for their completion.

Most of the goals on the timeline have not been completed.

Levin is also sponsoring a resolution, one of two competing measures that oppose the president's plan to increase force strength in Iraq by more than 20,000 troops.
