I was wrong about Trump (Ad)

I made a mistake. A mistake I feel very foolish about. After speaking with Donald Trump and some of his advisors, I believed him. I believed the promise that he would finally confront the single most dangerous threat to American life. That he would fix the ticking time bomb I’ve been warning about for 15 years. But I was wrong.

Let me show you exactly what we’re doing to prepare.
