The U.S. Department of Veterans Affairs has approved more than 20,000 claims for Coloradans under a new law designed to boost health care coverage for veterans exposed to toxins and burn pits while serving overseas. The figures come as President Joe Biden on Tuesday celebrated 1 million claims granted since he signed the PACT Act into law nearly two years ago. “We can never fully thank you for all the sacrifices you’ve made,” Biden told veterans in New Hampshire on Tuesday.
