WASHINGTON (AP) — The battle continues between House Republicans and Senate Democrats -- and even among Republicans themselves -- over legislation that would prevent government agencies from closing next week.

The Senate today approved that legislation, after stripping out a provision blocking money for President Barack Obama's health care law.

Some Senate conservatives tried to block final passage -- a move opposed by many Republican lawmakers who were worried that the tactic would only enhance the chances of a government shutdown for which Republicans would get the blame.

It remains unclear whether the Senate and the Republican-run House will be able to complete a compromise bill in time to get it to President Barack Obama for his signature before the government has to close.
