Congressional leaders have struck a deal to avert a government shutdown this week, agreeing to punt a pair of funding deadlines later into March to buy more time for spending talks. Under the deal announced Wednesday, leaders have agreed to extend funding for six full bills covering the departments of Agriculture, Justice, Commerce, Energy, Interior, Transportation and Housing and Urban Development through March 8. The deal would also extend funding for the remaining six annual funding bills, which cover the departments of Labor and Health and Human Services, the Pentagon and other offices, through March 22.
