On the same day President Barack Obama signed healthcare reform legislation into law, 13 Republican state attorneys general filed a federal lawsuit against the overhaul.

Florida Attorney General Bill McCollum, who is running for governor, filed the suit in federal court in the state's northern district. Attorneys general from South Carolina, Nebraska, Texas, Louisiana, Alabama, Michigan, Colorado, Pennsylvania, Utah, Washington, Idaho and South Dakota also signed on.


Several of the officials announced Monday they would pose a legal challenge to the healthcare bill they believe violates the Constitution. 

The suit represents only one means by which Republicans are still attempting to thwart the massive healthcare bill. Republican Sen. Jim DeMint (S.C.) and Rep. Steve King (Iowa) introduced legislation that would repeal the legislation.

The suit specifically claims that the Medicaid expansion, individual mandates to buy health insurance and several tax provisions violate various clauses in the Constitution. They say that the measures run roughshod over guarantees of state sovereignty and limitations on the scope of taxation.

Several Democratic leaders have said that the bill falls within constitutional bounds. 

Republican leaders, such as Senate Minority Whip Jon Kyl (Ariz.), predicted several weeks ago that legal challenges would be made to the legislation should it pass.

McCollum is not the only attorney general who is party to the case and also seeking higher office. Michigan AG Mike Cox is also running for governor.
