WASHINGTON - "Stand Your Ground" laws are under fire on Capitol Hill.
Oklahoma is one of the 30 states that have this type of law on the books.
A Senate committee heard testimony Tuesday from Sybrina Fulton, the mother of Trayvon Martin.
Martin was shot and killed last year in Florida by George Zimmerman, a neighborhood watch captain.
Fulton says "Stand Your Ground" laws are doing more harm than good.
She also has the backing of Democrats who are wanting a federal review in the 30 states that have the law.
Meanwhile, Republicans say it is an extension of a fundamental right.
Sybrina Fulton, Trayvon Martin's mother, said, "The person that shot and killed my son is walking the streets today and this law doesn't work."
Sen. Ted Cruz, (R) Texas, said, "Self defense is a bedrock of liberty."
Even with this hearing, "Stand Your Ground" is likely to stand as-is considering that election season is just months away.
