Senate Democrats appear to be lining up support for the so-called nuclear option in changing Senate rules to curb filibusters. Democrats are furious about Republican blocks on federal judicial nominees.

Senate Democratic leader Harry Reid has taken steps to alter the filibuster rule in the Senate.

"It's time to get the Senate working again. Not for the good of the current Democratic majority, or some future Republican majority, but for the good of the United States of America," Reid said. 

But, Republican leader Mitch McConnell says Reid wants one set of rules for Democrats and one for Republicans.

"He may as well have just have said, 'If you like the rules of the Senate you can keep them,'" McConnell said. 

The rule change would alter the procedural threshold for judges from 60 votes to a simple majority of 51.
