Hundreds of thousands of Americans are gathering for nationwide rallies in support of tighter gun control. March For Our Lives grew out of a movement calling for change after 17 people were killed by a gunman at a high school in Florida last month. On Friday, the White House said it would ban bump stocks, which give semi-automatic guns rapid-fire capability.

The proposal defines an assault weapon as any semiautomatic rifle that has the capacity to accept a detachable magazine, and any feature like folding or telescoping stock, or that can accept more than 10 rounds of ammunition.

Republican state senators on Monday afternoon rejected a bill from Democrats that would have banned bump stocks in Colorado. Senate Bill 51 failed on a 3-2, party-line vote in the Senate State, Veterans and Military Affairs Committee. The measure would have created a ban on the devices, which can increase a semi-automatic rifle’s rate of fire to near what an automatic firearm can discharge. Bump stocks were used by a gunman who killed 58 people and injured hundreds more in October at a country music festival in Las Vegas.

The National Rifle Association sued in federal court Friday to block a new Florida law, just signed by Gov. Rick Scott, that prohibits gun sales to anyone under 21. "We filed a lawsuit against the state for violating the constitutional rights of 18- to 21-year-olds," said Marion Hammer, lobbyist for the NRA in Florida. NRA lawyers in Tallahassee and Washington, D.C., were working on the complaint Friday afternoon, and filed the complaint moments before the court's deadline.

Weeks before he killed 17 students and staff at Marjory Stoneman Douglas High School in Parkland, Fla., Nikolas Cruz bought an AK-47-style rifle at a gun shop. While he didn’t use it during his killing spree on Feb. 14, his purchase drew attention to civilian versions of one of the most famous Russian inventions of the 20th century, the AK-47. In late February, shortly after the shooting, a small group of protesters gathered at a large, nondescript warehouse in Pompano Beach, about 13 miles from Marjory Stoneman Douglas.

Birmingham Police Chief Orlando Wilson said the shooting left a 17-year-old girl dead and a 17-year-old boy wounded.

A Las Vegas billboard was vandalized to read, "Shoot a school kid only $29," early Thursday morning. The billboard originally read, "Shoot a .50 caliber only $29."

More than 57,000 guns were turned over in Australia last year, the BBC reported. The guns were handed in during a three-month national amnesty during which Australians could turn over guns without fears of prosecution as part of an effort to limit the amount of illicit weapons in the country.

Crown-wearing worshippers clutching AR-15 rifles drank holy wine and exchanged or renewed wedding vows in a commitment ceremony at a Pennsylvania church on Wednesday, prompting a nearby school to cancel classes.

Walmart announced Wednesday that it is raising its age restriction to 21 for firearm and ammunition purchases. The company said in its statement that it made the decision in light of recent events and will try to implement this change "as quickly as possible."
