Congressional leaders will move next week to pass a two-tiered stopgap into March, with six days left until the first of two government shutdown deadlines.

The new funding patch would keep federal agencies running on two different timeframes, like the current stopgap. Funding for some federal agencies would expire March 1, while funding for others would run through March 8, according to a source familiar with the proposal.

Speaker Mike Johnson is backing the plan, which is necessary to finish a slate of 12 spending bills for the current fiscal year, after he previously rejected the notion of another short-term funding extension. Johnson is expected to brief the GOP conference on Sunday night.
