Pensacola Rep. Mike Hill is attempting to repeal the gun control measures passed last year in the wake of the massacre at Marjory Stoneman Douglas High School in Parkland 11 months ago.

The bill would lower the age to buy a gun from 21 back down to 18 and remove provisions that created a three-day waiting period for rifle and shotgun sales; that banned bump stocks that can allow a semi-automatic rifle to fire like a fully automatic rifle; and that created the ability for law enforcement to seek risk-protection orders to seize guns from people declared dangerous.

Hill filed the bill, HB 175, with the Florida House of Representatives on Monday.

The Marjory Stoneman Douglas High School Public Safety Act passed the Florida Legislature last year with bipartisan support and was signed into law by Gov. Rick Scott in March. The law was passed weeks after Parkland shooting survivors, family members and supporters filled the halls of the statehouse in Tallahassee demanding action in response to the Feb. 14 shooting, which killed 17 people.

The bill provided $500 million for school safety measures but also enacted changes to Florida's gun laws that have been decried by pro-gun rights groups.

Florida Gun Rights, a group that calls itself the only "no compromise" gun rights group in the state, praised Hill in a press release for filing his bill.

"Rick Scott and Florida lawmakers punished law-abiding gun owners for the actions of a criminal with the passage of SB 7026,” said DJ Parten, director of legislation for Florida Gun Rights, in the release. "I applaud Rep. Hill for filing this important legislation to restore the rights of law-abiding Floridians and look forward to working with him to advance it."

Hill told the News Journal he thought the provisions in the law passed last year violated the Constitution's Second Amendment, and he had made a campaign promise to file a bill repealing the gun control portions of the law.

Hill said his oath to uphold the Constitution is something he takes seriously.

"I see an oath as an act of worship between me and the living God," Hill said. "And I fear that God enough to maintain my oath that I give to him. That's why I'm very reluctant to say an oath unless it is of the utmost importance."

Hill said he's not sure if the bill will move forward, but he feels he kept his oath by filing the bill. He added that the law passed last year under "emotional mob rule."

"When you have a large group of people — and I'll call it a mob — when you have a large group of people there that are running on emotion only, that's when decisions can be made that perhaps would not have, when you sit back, like in this case, properly vetted that bill," Hill said.

Hill won re-election to the Florida House in November after winning the Republican primary for the seat. Among his campaign promises was a pledge to bring President Donald Trump's Hollywood Walk of Fame star to Pensacola. Trump's star remains in Hollywood.

When asked for an update on the Trump star, Hill said the issue has nothing to do with the gun bill. He said he's been following what is being done with the star in Hollywood.

"We'll see," he said.

Hill has also filed two other bills ahead of the session, one protecting Confederate monuments and one banning the use of red -light cameras to issue tickets.

Hill's gun bill has already drawn sharp criticism online from Parkland students and parents.

Parkland shooting survivor and gun control activist David Hogg posted a video to Twitter on Tuesday saying if Hill's bill passed, it would be "an absolute f---ing disaster" and urged people to email Hill to voice opposition.

"For the thousands of kids that went up to Tallahassee and worked their ass off to get these laws passed, the least that they could do is not try to reverse them their first year back in office," Hogg said in the video.
