Secretary Markwayne Mullin on Instagram: "Another busy week at DHS. I testified before Congress on our department’s agenda and how we’re working to protect our homeland. Yesterday, I had the privilege of joining a ribbon cutting for an @uscg facility designed to educate our Coast Guard men and women on new and emerging technologies. As always, it’s an honor to serve under @potus Trump as we deliver on the American people’s mandate to Make America Safe Again 🇺🇸"
