Jackson Lee also released a statement on Thursday that said the attack has "once again raised the "growing concern of intolerance and a form of domestic terrorism we are finding more common since the attacks on Sept. 11, 2001.

"We cannot tolerate this in America," she added. "This was not the first incident in the Sikh community and there are numerous others including an attack that occurred just days after the 2001 terrorist attack in which a Sikh owner of gas station in Mesa, Ariz., was killed."

She also called for a "national conversation" about how to prevent gun violence, and called on elected officials and those running for office this year to offer "real plans to do something about it."
