U.S. Sen. Joe Donnelly, D-Ind., says even though the filibuster has been abused in recent years, his party should seek a consensus with Republicans before changing the chamber's rules.
Critics have complained that the filibuster is too often used to block important votes. Since 2007, the GOP has used the parliamentary tactic to block legislation and nominees an unprecedented 386 times.
In the last weeks of 2012, Democratic Leader Harry Reid and Republican Leader Mitch McConnell jousted over whether to restrict filibusters.
Donnelly says the negotiations to address the dysfunction should continue, and that Reid should find a general agreement with the GOP.
"He will be talking with our Republican friends over the next week or two to try to see if there is a consensus that can form, and I am hopeful that can happen," he says.
