Under current law the State Dept. can revoke the U.S. nationality of Americans who formally renounce their citizenship, become citizens of or pledge allegiance to foreign nations, engage in hostilities against the U.S., or are convicted of treason. We do not need to create a situation were we are calling groups terror groups (who defines?) and stripping citizenship. Want to revoke someone's citizenship, bring them up on charges of treason. The law is already there!
