"Is crack worse for a person than marijuana?" Polis asked Leonhart.
"I believe all illegal drugs are bad," Leonhart answered.
Polis continued, asking whether methamphetamines and heroin were worse for a person's health than marijuana.
"Again, all drugs, they're illegal drugs," Leonhart started, before being cut off by Polis.
"Yes, no, or I don't know?" Polis said. "If you don't know, you can look this up. You should know this as the chief administrator for the Drug Enforcement Agency. I'm asking a very straightforward question: Is heroin worse for someone's health than marijuana?"
Leonhart ducked again, repeating, "All illegal drugs are bad."
