Democrat Colorado Gov. Jared Polis, the nation's first openly gay man to be elected as a state governor, signed the bill into law.
"Colorado has joined a growing list of states that have banned so-called conversion therapy," Polis wrote in a social media post. "It's a tortuous practice that has long been widely discredited by medical and mental health professionals."
Chiles sued Colorado officials in 2022 to block the conversion therapy ban, arguing among other things that the law unlawfully discriminates against her speech "on the basis of the content of the message she offers."
