Sen. Tom Coburn (R-Okla.) has put a hold on Senate Democrats' continuing resolution to fund the government past March 27, and Senate Majority Leader Harry Reid (D-Nev.) isn't happy about it.

Reid said at a news conference Tuesday that Coburn has put a hold on the bill, which prevents it from coming to a vote, and Coburn's office has confirmed the hold to Post Politics.

Coburn said he merely wants time to read the bill.

"To not allow us the time ... to be able to read and study the bill is really going against the best traditions of Senate but also it goes against common sense," Coburn said. "How do we know whether we want to offer amendments to the bill if we haven't read the bill?"

Coburn said he plans to let the bill move forward once he has read it.

But Reid wasn't happy. He expressed his frustration with Coburn -- the two have battled frequently -- on the Senate floor shortly thereafter.

"It's a 587-page bill. It has been available to the public, because the vast majority of this bill is" the same as the House version, Reid said. "I'm trying to be not too sensitive, but the senator from Oklahoma seems to have a problem."

Reid then read some of Coburn's recent comments complaining about Senate leadership, adding: "One day he should look in the mirror."

Sen. John McCain (R-Ariz.) defended Coburn, arguing that Republicans shouldn't take it on faith that Senate Democrats' bill is basically the same as House Republicans' continuing resolution.
