She lied, Congress isn't her employer, such protections are thus irrelevant. Too bad for you folks.Arrested for what? Was she a juvenile at the time of the arrest? Was it a false arrest? Was she indicted and brought to trial? Or did she do a plea deal? Was it a misdemeanor?
So much is unknown....
The LAW states she can legally answer NO, to an employer asking her if she was ever arrested, if her arrest was expunged.
