When anyone applies for a job nowadays he or she must provide a valid ID and SS card at the very least, and more often than not a signed release so the prospective employer can obtain the scholastic records. For anyone applying for a position where he or she will be dealing with sensitive material, the background check is more detailed, and besides the above, a passport history and medical history as well as any documents containing any other name the person may have gone by will be required for review by the prospective employer. Of course, almost any employer will run a criminal background check.
The Obamunist applied for the most sensitive and high-profile job on the planet, and yet he and his minions and enablers would want us to waive any background check.
