There are moments when silence is not an option. My wife, Robin, a retired Brigadier General, and I, a retired Army Colonel, have spent our adult lives in uniform and in public service.

Fortunate to join my colleagues and Speaker Rivas to celebrate new state funding for immigration services here in our community through Catholic Charities. This administration continues to target people with no criminal record who are simply trying to build better lives for their families.

Trump’s half-baked AI executive order will block states from protecting children and families while offering zero safeguards. Rather than “removing barriers,” this order creates a reckless free-for-all that puts kids at risk.

This is beyond shameful. Pete Hegseth should be absolutely ashamed. The idea that we’d authorize killing civilians — again — shows he’s never bothered to read real history. We’ve seen this before in WWII. You don’t target innocent people. Ever.
