Driving the news: Sullivan spent the legislative session pushing bills to expand Colorado's red flag law and tighten restrictions on so-called ghost guns. Polis signed both measures into law.

• One expands who can ask courts to temporarily remove firearms from people deemed a danger to themselves or others.
• The other cracks down on homemade and 3D-printed weapons by barring most people from manufacturing potentially functional firearms.

Yes, but: Democrats stripped a provision from the ghost guns bill that would've banned distributing 3D gun-printing instructions after Polis warned he would veto the measure.

• In addition, a bill to tighten regulations on the sale of gun barrels died when lawmakers adjourned earlier this month.

What he's saying: Sullivan says he wanted to do more to prevent shootings like the one at Evergreen High School last year, including tougher safe-storage requirements and increased penalties for violations.

• The lawmaker said he's "really looking forward to the next [governor's] administration to see where they might land" on gun legislation.
