Colorado State Representative Tom Sullivan (D-Centennial) is facing a recall.

The Colorado Secretary of State's Office approved the language on a petition to recall Sullivan on Monday. The organizers need 10,035 signatures by July 12 to get the recall effort moved to a ballot.

Sullivan is best known for sponsoring the red flag gun control law in memory of his son, Alex, who was killed in the Aurora theater shooting in 2012. The legislation allows for someone's guns to be temporarily taken away if a court determines that person is a danger to themselves or others. Governor Jared Polis (D) signed the law last month, but it doesn't take effect until next year.

Kristine Brown is named as the person behind the recall petition on the SOS website. Colorado Politics, 9NEWS' content partner, reports it's the same Kristine Brown who serves as the vice chair of the Colorado Republican Party.

The Rocky Mountain Gun Owners, a pro-gun rights organization and lobbying group, said in a tweet on Sunday that there will be "a brutal series of recalls targeting scandal-ridden Democrats who voted for the deadly 'Red Flag' gun confiscation bill." They teased ahead to new developments.

RMGO recently filed a lawsuit against the red flag law. They specifically mentioned funding an effort to recall Sullivan at the announcement of the suit.

Sullivan isn't the only state lawmaker who's been in danger of a recall this year. Opponents also started a petition to recall State Rep. Rochelle Galindo (D-Greeley), but she resigned over the weekend. In a Facebook post, she said she came to that decision after allegations were made against her.
