As the son and grandson of veterans, Representative Casten holds in highest regard those who put their lives on the line to defend our freedoms. Rep. Casten is committed to ensuring that the men and women who have served, are serving, or will serve in the U.S. military get the resources and care they need – both at home and abroad. He knows that our veterans' service is a debt that can never be fully repaid and is a solid advocate for making sure they receive the benefits they have earned.

In Congress, he is committed to supporting programs that better enable our servicemembers to transition back into civilian life, have access to both mental and physical health care, and provide resources for our military families while their husbands, wives, fathers, mothers, sons, and daughters are deployed.

Rep. Casten was proud to co-sponsor the Honoring our PACT Act of 2022, signed into law by President Biden, which addresses health care, presumption of service-connection, research, resources, and other matters related to veterans who were exposed to toxic substances during military service. Additionally, he’s a co-sponsor of the Vet CENTERS for Mental Health Act of 2023, which improves access to mental health facilities for veterans.

Rep. Casten also takes pride in constituent services related to veterans affairs. He’s helped obtain the status of VA claims for service-related disabilities and worked to retrieve service records and missing awards and medals for veterans.

Each year, to recognize those who served our country, Rep. Casten runs a "Valentines for Vets" program to collect cards for veterans. In February 2024, Rep. Casten delivered over 400 cards to the Oak Lawn VA clinic.
