Rep. Michele Bachmann chastised President Obama for his monarchical ambitions after his State of the Union address Tuesday night and warned that House conservatives were preparing to sue the president if he went too far in exercising his executive power.

“He’s the president of the United States. He’s not a king,” Bachmann said following Obama’s speech, the Daily Caller reported. “He may think he’s a king, he may declare himself king, but that’s not what he is under our Constitution.”

Bachmann foreshadowed pending litigation if Obama proceeded with the numerous executive actions that he announced during the address.

“If he wants to move forward with this unilateral activity, he better be prepared for the lawsuit that the United States Congress will bring to him,” she said, and the National Journal reported that other GOP lawmakers, including Rep. Steve King (R-IA) also voiced support for legal action.

A Bachmann aide pointed the Daily Caller to existing legislation, introduced in December by Rep. Tom Rice (R-SC), as the potential avenue for instigating a lawsuit against the president. The bill endorses “a civil action for declaratory or injunctive relief to challenge certain policies and actions taken by the executive branch.”
