More green groups join effort to change Senate rules

“Whereas Senators once resorted to filibustering only in rare and exceptional instances of intense opposition, rampant obstruction has now transformed standard operating procedure. Today, majority rule in the Senate is the exception, not the rule,” said the letter to Senate Majority Leader Harry ReidHarry ReidCongress departs for recess until after Election Day How Congress averted a shutdown Congress steamrolls Obama's veto MORE (D-Nev.) and Sens. Dick DurbinDick DurbinDems gain upper hand on budget McConnell: Senate could drop flood money from spending bill Funding bill rejected as shutdown nears MORE (D-Ill.) and Chuck SchumerCharles SchumerCongress departs for recess until after Election Day Democrats press Wells Fargo CEO for more answers on scandal 78 lawmakers vote to sustain Obama veto MORE (D-N.Y.).

Among the group's recommendations are ending the ability to filibuster motions to proceed, requiring senators who want to block bills and nominations to take the floor and allowing 41 senators to vote to continue debate.

“Requiring those wishing to slow down or halt legislation through the Senate rules to do so publicly on the Senate floor would raise the costs of obstruction so that the filibuster is reserved for instances in which a dedicated minority is intensely opposed to legislation,” the letter said.
