The D.C. police confirmed reports Wednesday that they are looking into an incident in which David Gregory, the host of the television show “Meet the Press,” displayed what he described as a high-capacity ammunition magazine.

Asked about media reports saying that authorities were looking into the incident, Gwendolyn Crump, the police spokeswoman, responded early Wednesday by e-mail: “Yes. We are investigating this matter.”

The incident came as Gregory was interviewing Wayne LaPierre, the CEO of the National Rifle Association, about measures that Gregory suggested might reduce the potential for mass killings, such as the one that occurred in Connecticut. .

In asking his guest on the NBC show whether high-capacity ammunition magazines should be banned, Gregory held an object in his hand and said it was a magazine that could hold 30 bullets.

In its firearms regulations, the The D.C. Code stipulates that “No person in the District shall possess, sell, or transfer any large capacity ammunition feeding device” whether or not it is attached to a firearm.

“Meet the Press,” generally is produced in the District.

After the TV show aired, references to the incident began to appear online, questioning whether the code had been violated.

Reports about the incident aired Tuesday on media outlets. Some of the reports indicated that police would try to determine whether the object was an actual high-capacity magazine.

At the hour at which reports of the inquiry were confirmed early Wednesday, it appeared impractical to obtain response from the television show, or the NBC network which carried it.
