Republican lawmakers are asking governors to support the repeal of President Obama’s healthcare reform law by refusing to implement its provisions.

Sen. Jim DeMint (R-S.C.) and Rep. Michele Bachmann (R-Minn.) are leading the group, which focused on the law’s state insurance exchanges in a letter released Monday.

“By refusing to create an exchange, you will assist us in Congress to repeal this violation which will help lower the costs of doing business in your state,” the lawmakers wrote to governors.
