Congress is poised to miss another self-imposed deadline to release legislative text for the final spending package to avoid a partial government shutdown this week, with disagreements on how to fund the Department of Homeland Security a top sticking point.

Lawmakers had wanted to release the text of the deal on Sunday to give the House the necessary 72 hours to schedule a vote. But that target was missed over the weekend and Monday proved also unsuccessful over lingering disagreements about the homeland bill with time running out to clear pending legislation through both chambers before midnight on Friday.
