Sen. Rick Brattin, R-Harrisonville

Sen. Rick Brattin, R-Harrisonville, speaks during a Freedom Caucus news conference in January, accompanied by, from left, Sens. Denny Hoskins, R-Warrensburg, Nick Schroer, R-Defiance, Jill Carter, R-Granby, and Andrew Koenig, R-Manchester. Brattin, Hoskins and Schroer are being sued for defamation over social media posts after the Chiefs’ victory parade shooting.

The Kansas man suing three Missouri lawmakers for defamation is challenging their assertions that their statements accusing him of being involved in the shooting at the Kansas City Chiefs’ Super Bowl celebration were made in the course of official business.

In filings Monday in the federal lawsuits Denton Loudermill is pursuing against the three state senators, his attorneys demand a chance to test those assertions. Loudermill’s attorneys – Arthur Benson, LaRonna Lassiter Saunders and Katrina Robertson – filed three almost identical responses Monday to the motions for dismissal by state Sens. Nick Schroer, Rick Brattin and Denny Hoskins.
