Grosskreutz has filed a lawsuit against him and Wisconsin police and officials, alleging they "conspired" to let armed individuals patrol the streets and "mete out justice as they saw fit."

The Feb. 14 lawsuit seeks "damages for emotional distress, humiliation, loss of enjoyment of life, and other pain and suffering on all claims," and punitive damages.

Rittenhouse said news of the lawsuit was "very frustrating" and "upsetting." "This is, honestly, to me, an attack on our Second Amendment rights and our rights to self-defense," he said Wednesday on "Tucker Carlson Tonight."

"And it's saying if you use your God-given right to self-defense, they're going to come after you. If you went to court, you're acquitted, rightfully so, they're going to take you to civil court, and they're going to file. They're going to take you for everything you're worth. They're going to drive you into bankruptcy and drown you in a mountain of legal bills."

After Grosskeutz was shot, a friend of his, Jacob Marshall, posted a photo of them together in the hospital with the caption “can’t stop my boy.” In the comments section in the post, Marshall said “I just talked to Gaige Grosskreutz too. His only regret was not killing the kid and hesitating to pull the gun before emptying the entire mag.” When asked about those comments while under oath, Marshall opted to claim that he made up that quote - which seems unlikely given Grosskreutz’ actions before getting shot.
