The Republican governors of Oklahoma and Arizona signed bills banning transgender athletes from girls' school sports on Wednesday, joining a growing list of states that have passed or enacted similar laws on a contentious election-year issue.

Arizona Gov. Doug Ducey also signed a bill banning irreversible gender reassignment surgery for minors.

"This legislation is common-sense and narrowly-targeted to address these two specific issues ⁠— while ensuring that transgender individuals continue to receive the same dignity, respect and kindness as every individual in our society," Ducey said in a statement.
