Senator Marco Rubio's first filed amendment seeks to enhance our national security. Naturally this entails trying to nullify a recent Obama Executive Order. Last month president Obama, finally despairing that the U.S. legislature could scrounge enough votes to rescue Castro's regime, signed an executive order further opening U.S. travel to Cuba, and thus further enriching Castro's spy, military and security forces, who own Cuba's "travel industry." The Executive order will open more U.S. airports to direct flights to and from a nation our own State Department classifies as a state sponsor of terrorism.
