Leaders in both parties are racing to secure a deal on government spending as the negotiation window quickly closes and the fears of a shutdown grow more pronounced.

Congress returns to Washington next week facing a pair of looming funding deadlines — March 1 for a handful of agencies and March 8 for the rest — leaving lawmakers with little time to iron out their differences and get bills to the floor to keep the government open.

While Speaker Mike Johnson (R-La.) has moved deftly to avoid a shutdown since taking the gavel in October, restive conservatives are losing patience with his willingness to cut budget deals across the aisle. And some observers on Capitol Hill are already warning that the current fight is the greatest shutdown threat of this Congress. 

“I’m worried. Of all the scares we’ve had since the last fiscal year, I think this is going to be the scariest. I think we could be in a world of hurt,” said a Senate GOP aide. “I don’t know if it’ll be a partial or a full, but I think the chances of a shutdown are the highest we’ve had this fiscal year.”
