Greg Brophy, Colorado State Senator, Proposing Bill To Legalize Alcohol For 18-Year-Olds Under Parental Supervision

In November, Colorado voted to regulate marijuana like alcohol, and now a state senator is proposing a bill to legalize public consumption of alcohol for 18-year-olds under parental supervision.

Greg Brophy (R-Wray), told the Associated Press he got the idea after he and his wife took his daughter out for her birthday and couldn't buy her a drink because she was one year shy of 21.

In an interview with Fox News' Ship Smith, Brophy said he thought the bill could be tough to pass.

"A lot of legislators love the idea, but after the special interests groups, you know, turn loose on it, who knows what'll happen," Brophy said.

When Smith asked Brophy what kinds of special interest groups he was talking about, Brophy responded, "Well you'll end up with Mothers Against Drunk Driving of course," adding later that there are groups who just "don't like that demon rum."

However there are groups outside of MADD that have expressed concern about the bill.

"It puts all the burden of making the decisions of who can and can't be served onto our servers and our operators," Pete Meersman, CEO of the Colorado Restaurant Association told ABC News.

Currently there are 11 states -- Connecticut, Kansas, Louisiana, Massachusetts, Mississippi, Nevada, New York, Ohio, Texas, Wisconsin, Wyoming -- that allow 18-year-olds to drink alcohol with parental approval.

Brophy posted on his Facebook page on Wednesday:

I have heard from some who really hate this bill. I find the opposition interesting.
To me it seems to stem from a general opposition to alcohol which is understandable but I'd say a lost cause and a settled question. I want to respectfully ask those opposed, to set aside the anti-alcohol stance and reflect upon the question: why is it appropriate for the State to deny parents the ability to show their adult kids how to responsibly consume adult beverages in a public setting? Those same kids are often turned completely loose to attend college hundreds of miles from home and completely unsupervised. Those same kids will be able to consume adult beverages completely unfettered on their 21st birthday. (ignoring the fact that they will have nearly unfettered access between the time they leave your home and that 21st birthday) Why on earth would you want to deny responsible parents the chance to expose their own kids to the effects of this product while with their parents?

In Colorado currently, 18-year-olds may drink alcohol on private property with parental consent.
