TOPEKA, Kan. (AP) — The Kansas Attorney General’s Office has asked Kansas Lottery officials to review some proposed regulations needed before legalized sports gambling can begin in the state.

The attorney general’s office approved three proposed regulations but returned others to the Kansas Lottery after “identifying specific shortcomings that must be remedied,” John Milburn, a spokesman for Attorney General Derek Schmidt, said in a news release Friday.

The returned regulations generally involve such things as legal definitions, marketing agreements and advertising rules.

Kansas officials announced Thursday that legalized sports betting would begin at four state-owned casinos on Sept. 1.

Kansas Lottery Executive Director Stephen Durrell told KSHB-TV on Friday that he is confident the revisions will be made in time for the Sept. 1 target date.

When Kansas lawmakers approved sports wagering this year, they removed oversight of proposed regulations from other state agencies, leaving only the attorney general’s office to check for errors made “in the hurried drafting of regulations that affect millions of dollars in wagering activity, and we take that responsibility seriously,” Milburn said in the statement.

The attorney general’s office is expediting its review of proposed regulations submitted by the Kansas Racing and Gaming Commission, Milburn said.
