Sen. Frank Lautenberg (D., N.J.) will propose a rule that would require Senators to phyiscally hold the floor and speak on a bill in order to sustain a filibuster:

“Filibusters should happen on Capitol Hill, not from the Capital Grille. If any of my colleagues feel strongly enough about a bill or nomination to stop all work in the Senate, they should have no problem standing on the Senate floor to explain their opposition to the American public,” said Lautenberg, D-N.J.

Of course, the rule change would be subject to a 60-vote cloture procedure, and would require 67 votes to pass. The bar would be lowered significantly at the beginning of the next Congress in January 2011, however. At that point, only a simple majority will be required to change the Senate’s standing rules.
