More than 1,000 first responders from across the country threw their support behind net neutrality protections on Tuesday, with a letter demanding that lawmakers in Congress pass the Congressional Review Act (CRA) resolution to reverse the Federal Communications Commission (FCC)’s repeal of net neutrality.

“We are joining with millions of businesses, veterans, and Internet users in asking Congress to use their Congressional Review Act (CRA) powers to restore the strong net neutrality rules and other consumer protections that were lost when the FCC voted to repeal its 2015 Open Internet Order,” reads an letter endorsed by the internet freedom advocacy group Fight for the Future.

The letter comes days after Californians got a first-hand look at how their lives are already being affected by internet service providers (ISPs) that are unencumbered by net neutrality rules, which prohibit companies like Verizon and Comcast from slowing down internet speeds and creating paid “fast lanes” for wealthy internet companies.
