I wrote about the National Defense Authorization Act of 2012. In my opinion, the Senate made a huge mistake. Politifact has decided that Ron Pauls comments regarding this legislation are mostly false.
Go ahead and read it for yourself. By page 428 you will notice that the Secretary of Defense merely need submit a waiver which states you are a national security risk. That paragraph ensures that the provision stating that this entire process doesn't apply to US Citizens is null and void.
Politifact got it wrong.
