“Having a thoughtful discussion with gun owners in Texas about common-sense ways to reduce shootings, entirely consistent with Second Amendment rights, is a conversation we want to have because it’s everything we stand for,” Avery Gardiner, Co-President Brady Campaign to Prevent Gun Violence

Avery Gardiner, co-president of the Brady Campaign, said her organization reached out to the administration and wrote a letter to Attorney General Jeff Sessions offering their expertise after Parkland, but they never heard back.

With little movement in Congress, gun control advocates are turning to the private sector to drum up support for their cause. A new report from the Brady Campaign to Prevent Gun Violence has found that corporate America is increasingly taking a stance on firearms policy.

Avery Gardiner, co-president of the Brady Campaign, said the shareholder move appears to be unprecedented.

"I'm not aware of any other shareholder resolutions that deal with gun violence ever passing," she told CNNMoney. "They are making this something where they are literally putting their money where their mouth is."
