The 10 Democratic senators who crafted a healthcare compromise are keeping its details a secret, says Majority Whip Dick Durbin (D-Ill.) said Friday.

Responding to a complaint by Sen. John McCain (R-Ariz.) that Republicans haven't been told what's in the new bill, Durbin, the No. 2 Democrat in the Senate, responded that he's in the same position.

"I would say to the senator from Arizona that I'm in the dark almost as much as he is. And I'm in the leadership," Durbin said on the Senate floor.

Majority Leader Harry Reid (D-Nev.) has submitted the bill to the CBO from scoring, but Durbin said no one involved in the compromise will spill the beans until the score is released.

"We had a caucus after this was submitted to the Congressional Buidget Office where Sen. Reid and other senators who were involved in it basically stood up and said, 'We're sorry we can't tell you in detail what was involved here, but you will learn. Everyone will learn."

The reasoning behind the secrecy, Durbin said, is that "we want to basically see whether or not it works" before details become public.

The deal reportedly replaces the public option with a Medicare "buy-in" option for those aged 55-64 and a series of nonprofit healthcare policies modeled on the program federal employees get.
