The White House told gun-control advocates Tuesday that President Barack Obama’s wide-ranging gun control proposals will include a new federal gun trafficking law — long sought by big-city mayors as a way to keep out-of-state guns off their streets.
The proposal, which has not been discussed in detail by the White House up until now, will be unveiled Wednesday, along with Obama’s call for universal background checks for all new gun purchases, as well as new bans on assault weapons and high-capacity ammunition magazines, according to a person who was in the room for the presentation to gun control advocates. . . .
