Senator pressures Instagram to prohibit gun sales

Senator Edward Markey (D-Mass.) sent a letter to Instagram CEO Kevin Systrom on Monday calling on him to ban gun sales on the the popular photo-sharing service. Markey is the first U.S. Senator to join the campaign started by two New York State Assembly members in October. While Instagram is not a commerce website, the letter urges Systrom to prohibit sales in a manner "consistent with policies adopted by online marketplace entities such as Craigslist and eBay.”
