Chicago Mayor Rahm Emanuel is calling for a look into city pension funds to see if there are any investments in manufacturers or sellers of assault weapons. If there are investments in such companies, the mayor wants the city to divest from them.

City Comptroller Amer Ahmad says there are investments in a number of pools and that some do hold stock in companies that produce or sell assault weapons.

“We do know that there are some holdings, and they may not add up to a lot of money, but every dollar matters,” Ahmad said, according to the Chicago Tribune.

The mayor is hoping his move to look into city investments in assault weapons will prompt his counterparts across the nation to do so as well. 

Last week, Emanuel announced plans to introduce a gun control ordinance to the Chicago City Council this week.
