Nevada Democrats took aim at Energy Secretary Rick Perry on Thursday for secretly trucking weapons-grade plutonium cross-country to Nevada last year, vowing to introduce legislation to block the Trump administration from making any future trips.

“Not only did Secretary Perry and the agencies under his direction act in bad faith by totally ignoring the will of our Governor, their decision also completely disregards the health and safety of Nevadans,” said Democratic Sen. Catherine Cortez Masto.
