Our current policy of granting automatic U.S. citizenship to children of illegal aliens is insane , and ought to be stopped.
Representative Steve King (R-Iowa), who has an A+ rating  from Numbers USA, has introduced a bill to stop it, H.R. 140.

Now is the time to ensure that the laws in this country do not encourage law breaking.”...
