Welcome to Overnight Regulations, your daily rundown of news from the federal agencies, Capitol Hill and the courts. It's Tuesday evening here in Washington.

Here's the latest:

THE BIG STORY

Democrats are pushing hard against a Republican proposal to ease restrictions on purchasing gun silencers.

Rep. Jeff Duncan (R-S.C.) added his measure, known as the Hearing Protection Act to the Sportsmen's Heritage and Recreational Enhancement Act (SHARE), legislation aimed at broadening public access to federal lands for hunting and fishing.

Under Duncan's measure, silencers, also known as suppressors, would be removed from the National Firearms Act. Purchasers would need to only undergo a less extensive, instant background check.

Here's the fight on both sides:

Democrats say the measure will weaken gun safety laws and make active shooter situations more difficult to address.

David Chipman, senior policy advisor of Americans for Responsible Solutions, a pro-gun control group told members of the House Natural Resources Subcommittee on Federal Lands at a hearing Tuesday that the bill would make silencers more readily available to criminals.

"One of the reason we have not seen silencers out there in tons of crimes is the fact that we have a regulatory structure that makes it very difficult to get these," he said.

Republicans, however, claim sportsmen need silencers to protect their hearing.

"Right now we are in a situation where it seems … that sportsmen have to choose between damaging their hearing and being able to hunt, shoot, target practice," said Rep. Liz Cheney (R-Wyo.).

Stephen Halbrook, who has sued on behalf of the National Rifle Association, pushed back about claims that silencers will increase gun violence.

"If you want to make one now you can do it and a person who would not be dissuaded from committing a murder by capital punishment potentially is not going to worry about a National Firearms Act conviction for non-registration of a suppressor," he said.

Environment: The department of Homeland Security announced Tuesday that it has waived environmental and historical preservation laws to speed improvement of fencing on the border between California and Mexico.

Under the waiver, construction of border barriers near Calexico, Calif., won't be subject to federal regulations including the Endangered Species Act or the National Historic Preservation Act.

Rafael Bernal has the rest of that story here.

More finance: The head of the Consumer Bankers Association, a top banking group, is criticizing both parties for not installing a bipartisan commission to lead the Consumer Financial Protection Bureau.
