Senators worry gun bill could fizzle like immigration bill

Senate Republicans who are hoping for action on some kind of gun bill in the coming weeks are worried that the issue could go nowhere, just as immigration legislation went nowhere in the Senate in January.

Several ideas have some level of bipartisan support, including boosting background checks, banning bump stocks, and raising the minimum age for buying semiautomatic weapons from 18 to 21. But Republicans and Democrats are each looking to add language, and President Trump’s comments have created some uncertainty about what he wants to see in the bill, which has stalled the process so far.
