President Donald Trump’s inauguration gave congressional Republicans a once-in-a-generation opportunity to erase a spate of late Obama-era regulations — and they used it to make a significant dent before the legislative window closes in the coming week.

Since February, Republicans have used a once-obscure 1996 law to quash 13 "midnight" regulations on topics such as coal mining pollution, gun rights, internet privacy, Planned Parenthood funding, retirement savings and even bear hunting in Alaska. A 14th rule-blocking resolution is heading toward Trump’s desk, and GOP lawmakers hope to kill at least one more rule, on methane pollution, before the clock runs out May 11.
