This video frame grab image provided by”Meet the Press” shows host David Gregory holding what he described as a high-capacity ammunition magazine during Sunday’s program. Washington police say they are investigating an incident in which Gregory displayed the magazine on “Meet the Press.” Gun laws in the nation’s capital generally restrict the possession of high-capacity magazines, regardless of whether the device is attached to a firearm. Gregory held up the magazine as a prop for Sunday’s segment, apparently to make a point during an interview, even though D.C. police say NBC had already been advised not to use it in the show.
