H.Res. 639
H.Res. 639 is a bill that gives the Speaker of the House of Representatives the authority to start or join in on federal court cases to defend the constitutionality of U.S. immigration laws. It was introduced because some members of Congress believed that the Obama administration's immigration policies were not constitutional. Essentially, this bill allows the Speaker to legally challenge the executive branch if they think that immigration laws are not being followed properly.
