The Senate is putting the breaks on an effort to pass sweeping health care reform. As a result, negotiators say a bill may not be finished by the August recess as Democrats had planned.

Sen. Max Baucus, D-Mont., and Sen. Charles Grassley, R-Iowa, the two top lawmakers trying to write a bipartisan bill, have been unable to agree on several major issues, including whether to include a government-run insurance and whether to make it mandatory for employers to provide health insurance.
