An anti-gun bill that passed the House last week by a vote of 227 to 219 is likely to be enacted into law as soon as Tuesday.
House Speaker Kevin McCarthy (R-Calif.) announced the legislation, which will ban the purchase of certain semiautomatic assault rifles and high-capacity ammunition magazines, as he signed a proclamation on Wednesday.
It is one of several gun-control measures in the House that will have to be signed by President Donald Trump.
But McCarthy didn’t explicitly say what would happen if the House passed the measure, which would ban the sale of “assault weapons,” the same category of firearms that are already prohibited by federal law.
The House passed its version of the gun bill on a 235-191 vote on Monday.
The bill, which has no bipartisan support, was introduced by Rep. David Cicilline (D-R.I.) and Rep. Mark Meadows (R/C.O.M.) and passed by a narrow margin on the first day of debate.
But it is not clear that the bill will receive any Republican support.
It has been blocked in the Senate, which is controlled by the Democrats.
House Majority Leader Kevin McCarthy has long opposed any gun legislation that would impose a federal gun registration requirement.
He has said that any gun-safety measure that imposes such a requirement would violate the Second Amendment and that the United States is safer with a gun-free society.
The Brady Campaign to Prevent Gun Violence, which helped craft the Brady bill, called the House bill “the worst piece of gun-ban legislation in American history.”
The measure also would ban gun sales to certain federal contractors, including the Department of Homeland Security.
The ban would apply to anyone who has been convicted of a felony and who has received a “significant mental health or criminal history” or whose “personality disorder has been diagnosed or treated” by a mental health professional.
It would also bar any gun sales from federal contractors to people who are convicted of misdemeanors or crimes involving violence, sexual assault, kidnapping, assault, robbery, kidnapping with a deadly weapon, drug trafficking, domestic terrorism, domestic violence, weapons possession, and weapons use.
It does not prohibit gun sales by military members or certain federal employees.
The measure is not expected to face any serious legal challenges in the courts.
A number of Republicans have criticized the bill, saying it goes too far.
“The bill is not about stopping mass shootings or mass shootings.
The legislation is about closing loopholes that allow gun owners to buy guns and making it easier for criminals to obtain guns,” House Republican Conference Chairman Steve Scalise (R.-La.) said in a statement.
“It’s also a cynical attempt to circumvent Congress’ constitutional duty to keep our people safe.”
