Kansas Governor Laura Kelly on Thursday rejected a bill that would bar male students from competing against females in high school and college sports.

“As Kansans, we should be focused on how to include all students in extracurricular activities rather than how to exclude those who may be different than us. Kansas is an inclusive state and our laws should reflect our values. This law does not do that,” Kelly said in a statement.

The ACLU of Kansas has threatened litigation if the bill is introduced. In the bill’s fiscal note, the Kansas Attorney General’s office wrote that such a lawsuit would incur great cost for the state.
