Isakson urged the House to pass a CR with a resolution that states Congress will being doing appropriations every other year. He pointed to the fact that Congress hasn’t successful completed work on a budget and all 12 appropriations bills for years — forcing the need for CRs and omnibus spending measures.

“We’ve been traveling down the wrong road for far too long,” Isakson said on the Senate floor. “We’re here today in the conundrum we are because we didn’t do our job. … Four-years and running we’ve shirked our responsibility.”

Isakson has suggested in the past that if Congress did appropriations over two years, it would allow lawmakers to focus more on oversight and waste prevention during the off year. He said adding his idea to a CR could help garner enough support for passage in the House, which has not had an up-or-down vote on the Senate-passed “clean” CR.

It's unclear where the fight will go from here, with both sides digging in for the first government shutdown since 1996.
