Myrick said her concern was national security, not Hispanics in low-paying jobs.
"Our main concern is: Who's in our state?"
WHAT'S NEW: Rep. Sue Myrick filed a bill pushing to ban illegal immigrants from getting driver's licenses.
WHY IT MATTERS: Myrick says it would help national security; opponents say it won't keep illegal immigrants from coming to the state.
WHAT'S NEXT: Congress could take the bill up next year.
