From the Washington Times:

Senate Democrats refused to allow consideration of an amendment yesterday that would bar illegal aliens convicted of felonies from obtaining U.S. citizenship.
Democrats said the amendment would “gut” the immigration bill under consideration in the Senate and refused to allow a vote on it.
….
Democrats said the amendment is not necessary because crimes of “moral turpitude” such as rape and murder already prevent an illegal from obtaining U.S. citizenship, as would violations of drug laws.
Mr. Kyl came to the floor and listed the crimes he said would not be included without his amendment, such as burglary, assault and battery, possession of an unregistered, sawed-off shotgun, kidnapping and alien smuggling.

For Pedro’s sake!
