 A new New Hampshire law bans transgender athletes for grades 5 through 12 from teams aligned with their gender identity. The law requires schools to designate teams as girls, boys, or co-ed. Eligibility will be determined by birth certificates or other evidence. The governor signed the bill Friday. It should go into effect August 18th. Supporters say they're protecting girls. Advocates say it's diminishing rights for transgender children. I'm Ann Carrick, Fox News.
