Mark R. Levin, president of Landmark Legal Foundation, today issued a warning to the leadership of the U.S. House of Representatives about the possible use of the so-called "deem and pass," "self-executing," or "Slaughter Rule" to enact H.R. 3590, the legislative version of President Obama's healthcare proposal that has been previously approved by the Senate. If this tactic is employed, Landmark will immediately sue the President, Attorney General Eric Holder and other relevant cabinet members to prevent them from instituting this unconstitutional contrivance.
