Last week, I was the first United States Senator to step foot in Ukraine since Russia's invasion. I saw indisputable, chilling evidence of Putin's war crimes everywhere.

Here's what I saw — warning it’s graphic: Shallow graves filled with innocent civilians, women and children murdered by Putin. I will never forget the stench of death from the mass graves of innocent civilians.

Im at the southern border and last night I witnessed: Illegal immigrants preparing to cross the border—not a thing stopping them.
