Wyden's bill would require that law enforcement get a warrant in order to access your GPS data from telecommunications companies. Right now all they need is a subpoena, which a judge has never seen. He has support from Republican Congressman Jason Chaffetz of Utah, who ArsTechnica reports said:

"I take the Fourth Amendment very seriously. The law enforcement community is going too far..I happen to think that's wrong."

The bill would also make it a crime for individuals to access GPS data through spy applications or tracking software.

If the bill gets out of committee, it will face likely tough opposition from federal law enforcement. Under President Obama, the FBI has advocated for greater access to the private communications of Americans, and for fewer regulations tying their hands in investigations.
