Before 20 December 2019, will the U.S. Congress present the president with legislation banning the manufacture, possession, and/or sale of high capacity magazines for firearms?
In the wake of mass shootings in California, Ohio, and Texas, there has been increased political pressure for various gun control measures (Newsweek, CNBC). President Trump's potential support for particular gun control measures is a matter of speculation (The Hill, Axios, CNN). For the purposes of this question, a "high capacity magazine" is one capable of holding more than ten rounds. A ban need not cover all high capacity magazines to count toward resolution of the question.
