JEFFERSON CITY, Mo. (AP) — Two Missouri lawmakers have switched seats in the House chamber after one filed a restraining order against the other because he says they got in a fistfight.

Rep. Courtney Allen Curtis this week said Rep. Michael Butler swung at him outside a union reception over a dispute on a contested right-to-work bill. Butler has declined to comment.

Curtis was granted a restraining order against Butler. The two previously sat close to each other in the House chamber, where members vote and debate bills.

The Kansas City Star reports that House officials this week switched seating in the chamber to separate the two St. Louis-area Democrats.

Curtis was the only Democrat to vote last September in favor of enacting controversial right-to-work legislation that would have banned mandatory union fees.
