NBC “Meet The Press” talk show host David Gregory is under police investigation in Washington, D.C., for displaying an alleged 30-round magazine on Sunday’s program.

Metropolitan Police spokesman Araz Alali confirmed on Wednesday that the investigation is already under way, but couldn’t reveal more details at this time.

“There are laws in D.C. about possessing high-capacity magazine whether it is attached or unattached [to a weapon],” Alali said.

D.C. firearms code states that, “No person in the District shall possess, sell or transfer any large-capacity ammunition feeding device regardless of whether the device is attached to a firearm.”

The law describes large-capacity ammunition feeding device as a “magazine, belt, drum, feed strip or similar device that has a capacity of, or that can be readily restored or converted to accept more than 10 rounds of ammunition.”

“Meet the Press” is usually taped in Washington, D.C.

Gregory showed the high-capacity ammunition magazine on Sunday while interviewing Wayne LaPierre, CEO of the National Rifle Association, about gun control.

A representative for the network couldn’t be reached for a comment on Monday morning.

Gun control is back in the spotlight once again after a 20-year-old gunman allegedly shot and killed his mother and 26 people, including children, at the Sandy Hook Elementary school in Newtown, Conn., more than two weeks ago.

LaPierre, who doesn’t believe guns are the problem, has called for police and armed security guards in schools.

LaPierre has received considerable backlash, as some argue his response to the deaths is insensitive.
