Despite agreement on both sides of the aisle that the Iran nuclear agreement is not a treaty, a conservative activist group filed suit to block the measure as unconstitutional.
Freedom Watch announced the lawsuit on Thursday, arguing that by approving the Iran Nuclear Agreement Review Act, the Senate forfeited it's right to approve of a treaty's ratification by a two-thirds majority and changed the way treaties are ratified, who they are ratified by, and the required number of votes for approval.
"The Defendants gave away the carefully-crafted protections of the U.S. Constitution meant to preserve the liberties and 'provide for the common defense' of American citizens," the group said in a statement.
The suit names President Barack Obama for signing the review act and Sen. Bill Nelson, D-Fla.; Sen. Marco Rubio, R-Fla.; and Rep. Patrick Murphy, D-Fla., for voting in favor of the review act.
"These representatives acted in disregard of their obligations to uphold the U.S. Constitution," Larry Klayman, Freedom Watch's founder, said in the statement.
The administration and Congress argue that the agreement is not a treaty and therefore does not require a two-thirds consent of the Senate.
