On Capitol Hill, President Trump’s nominee for a high-level Pentagon post called it “insane” that civilians can buy semi-automatic rifles for personal use. Dr. Dean Winslow made the comment during his confirmation hearing Tuesday before the the Senate Armed Services Committee.

Dr. Dean Winslow: “But I’d also like to—and I may get in trouble with other members of the committee—just say, you know, how insane it is that in the United States of America a civilian can go out and buy a fully auto—well, a semi-automatic assault rifle like an AR-15, which apparently was the weapon that was used. And I think that’s an issue not as much for this committee, but elsewhere. So, again, obviously, you know, domestic violence—”

Sen. John McCain: “Dr. Winslow—”

Dr. Dean Winslow: “—is a serious problem.”

Sen. John McCain: “I don’t think that’s your area of responsibility or expertise.”

That last voice was Republican Senator John McCain, chair of the Senate Armed Services Committee.
