Senator Rob Portman is speaking out in favor of background checks and red flag laws to prevent gun violence. But he says that the senate will only act on a measure it knows the president will support.
Portman says he has conferred with senators Lindsey Graham of South Carolina and Richard Blumenthal of Connecticut.
A federal red flag law would allow police to obtain a court order to confiscate guns from potentially dangerous people.
Portman said such intervention would have been appropriate in the case of the mass shooting in Dayton early last month.
