This link is broken, either the page no longer exists or there is some other issue like a typo.
None of those links have any information about a specific new law or bill. They are all campaign platforms, the president alone cannot make law.
You stated "trying to pass" which would mean there is something in Congress right now, and that it's being "expanded" to cover specific items.
I'm in the "guns don't kill people, people do" crowd but I just can't stand all the paranoia that goes on with this subject. I am not a member of the NRA, namely since they tend to endorse political candidates who aside from being pro-gun are offensive to me on just about every other subject.
I'm also in Carolyn McCarthy's back yard. Her son getting killed by a mental patient does not qualify her to serve in Congress.
