By a 68-43 vote, the Illinois House passed a bill Tuesday that would outlaw sexual orientation conversion therapy in the state.
Of the 68 House members who voted in support of the measure, 61 were Democrats and seven were Republicans.
Under the Conversion Therapy Prohibition Act, HB 217, it would be illegal for mental health care specialists to perform conversion therapies on patients under the age of 18.
The bill, spearheaded in the House by state Rep. Kelly Cassidy (D-Chicago), still needs Senate approval.
In an email to supporters announcing the conversion therapy bill's passage in the House, Equality Illinois CEO Bernard Cherkasov said his organization supports the legislation because "it will protect LGBT youth in our state from ineffective and discredited attempts to change their sexual orientation and gender identity."
"In addition to us, every major mental health organization in Illinois supports the bill," Cherkasov added.
The Illinois General Assembly's regular scheduled session ends May 31.
