"Gun violence is an epidemic — it kills more than 30,000 people every year. Let’s strengthen gun safety provisions, not strip them," countered Sen. Dianne Feinstein (D-CA).
But Feinstein and Democrats were far short of the votes to stop the GOP plan, which now goes to President Trump for his signature.
Meanwhile, the House this week is ready to send five more "disapproval" resolutions to the Senate to get rid of various Obama Administration regulations.
"Congressional Review Act legislation provides relief for Americans hurt by regulations rushed through at the last minute by the Obama Administration," Speaker Paul Ryan said earlier this week.
President Trump will sign a second Obama rule reversal into law on Thursday, what's known as the "Stream Protection Rule," which Republicans charged would cost thousands of jobs in the coal mining industry.
On Wednesday, the House approved three rule reversals; two more are up for a vote on Thursday.
One of the plans approved on Wednesday in the House would roll back an Obama Administration rule that made it more difficult for states to require that people be drug tested in order to receive unemployment benefits.
