Kansas is joining a proposed compact with other states hoping to exempt themselves from the federal health care overhaul.

Republican Gov. Sam Brownback announced Wednesday that he signed a compact bill passed by the GOP-dominated Legislature earlier this month. The new law takes effect July 1.

The compact would let participating states remove themselves from all federal health regulations if Congress consents.

Many Republicans strongly oppose the federal health care law championed by Democratic President Barack Obama.

Critics of the bill questioned whether Congress would approve a compact. They also suggested member states could cut Medicare benefits for seniors. Brownback said the federal health overhaul represents a bigger threat.

The Texas-based group pushing the compact says eight other states have enacted similar laws, including Missouri.
