Pat Toomey thinks the Senate can get to 60 votes on expanding background checks on firearm sales. Lindsey Graham says a deal on red flag laws is imminent. And the White House has briefed senators on what options are on the table.

But everyone is still waiting on one person: President Donald Trump.

The Senate left Tuesday evening with no clear indication of what the next steps would be on gun legislation, in the aftermath of several mass shootings during the August recess. Nevertheless, senators involved in gun negotiations said they firmly believed the White House would come through with a proposal soon.

Among the proposals being discussed: Expanding background checks, grants for states to implement red flags laws, legislation from Sens. Toomey (R-Pa.) and Sen. Chris Coons (D-Del.) that would alert local authorities if people fail background checks and crackdowns on straw purchases.
