President Donald Trump signed an executive order Thursday pressuring states not to regulate artificial intelligence.
Trump and some Republicans argue that the limited regulations already enacted by states, and others that might follow, will dampen innovation and growth for the technology.
Critics from both political parties — as well as civil liberties and consumer rights groups — worry that banning state regulation would amount to a favor for big AI companies, who enjoy little to no oversight and that Trump's effort oversteps the limits of presidential power.
Here's what to know about states' AI regulations and what Trump signed.
What state-level regulations exist and why
Four states — Colorado, California, Utah and Texas — have passed laws that set some rules for AI across the private sector, according to the International Association of Privacy Professionals.
Those laws include limiting the collection of certain personal information and requiring more transparency from companies.
The laws are in response to AI that already pervades everyday life. The technology helps make consequential decisions for Americans, including who gets a job interview, a home loan and even certain medical care. But research has shown that it can make mistakes in those decisions, including by prioritizing a particular gender or race.
