"We've advocated that governments should put in place stronger regulations to govern the ethical use of facial recognition technology, and in recent days, Congress appears ready to take on this challenge," Amazon said in a statement.

On Monday, IBM said it was getting out of the facial recognition business.

Amazon said on Wednesday that it's banning use of its facial recognition software by police for one year, as pressure on tech companies builds to respond to the killing of George Floyd by a police officer in Minneapolis.

"We've advocated that governments should put in place stronger regulations to govern the ethical use of facial recognition technology, and in recent days, Congress appears ready to take on this challenge," Amazon said in a statement. "We hope this one-year moratorium might give Congress enough time to implement appropriate rules, and we stand ready to help if requested."

While the House Committee on Oversight and Reform has held a number of hearings on the use of facial recognition technology, it has yet to introduce a bill regulating the technology. Rep. Jimmy Gomez, D-Ca., who serves on the committee told CNBC in a phone interview he is hopeful Congress will pass a bill this year.
