A Missouri couple alleges in a federal lawsuit that they’re being denied the right to care for additional foster children because they are gun owners.

The Kansas City foster parents – James and Julie Attaway – already have one foster child and two biological children in their home, but say they want more, according to a report. Their lawsuit contends that state laws prohibit them from welcoming more foster children into their home if they possess or carry “loaded functional firearms.”

The Attaways say they fear losing their current foster child because of the laws.

“It leaves them with no actual ability to exercise their Second Amendment rights,” David Sigale, an Illinois lawyer who represents the couple, told the Associated Press. Similar lawsuits have been filed in Michigan and Illinois, he said.
