It has emerged that a registered child sex offender has been reading to children at Houston Public Library as part of its Drag Queen Storytime.

A group called Mass Resistance, which has been trying to put an end to the program and contacted KHOU about the pedophile.

The action group claimed that it had been asking the City of Houston for months to disclose information about the drag queens but got no response.

It was only after the group did their own digging that the shocking link was revealed.

The library has confirmed that one of the program's drag queens, Tatiana Mala Nina, is Alberto Garza, a 32-year-old child sex offender who in 2008, he was convicted of assaulting an eight-year-old boy.

'Most parents would not allow that individual to sit in this library and be held up as a role model to our children. Shame on you, Mayor Sylvester Turner!' said Tracy Shannon with Mass Resistance.

The Houston Public Library has now admitted that a proper background check on Garza was not carried out but what he will not be invited to participate in any future library programs.

Garza was charged with child sex assault in 2008. According to records, his victim was a child under the age of 14 years old.

The library said each program is supervised by staff, and all children are accompanied by a parent or guardian, the library said.

'In our review of our process and of this participant, we discovered that we failed to complete a background check as required by our own guidelines. We deeply regret this oversight and the concern this may cause our customers. We realize this is a serious matter,' the library said in a statement.

Protesters say they want people to be fired over the lack of oversight.

'If they had done their job and due diligence, if they had said wait...maybe it's not a good idea to have a sex offender who at 200 pounds and 5-foot-11 assaulted an 8-year-old boy!' Shannon said.

'We may not all agree that having adult entertainers is the right way to entertain young children or promote literacy and adversity and acceptance and inclusion,' she continued, 'but we can all agree that it's inappropriate to have a sex offender. And for someone to not do their due diligence, to have a sex offender entertaining children at the library.'

Drag Queen Storytime is part of a national program that aims to promote love and acceptance.

The storytimes are supervised by staff. Theibrary said. The library said Friday that a review revealed the volunteer never completed a background check before he was allowed to participate in the program.

Despite opponents of the scheme suing the library and Mayor Turner, the lawsuit was dismissed by a judge in January.

Houston Public Library released the following lengthy statement:

'We were made aware today that one participant for Drag Queen storytime who read at the September 29, 2018, Drag Queen Storytime has a criminal background that should have prevented him from participating in the program.

'We assure you that this participant will not be involved in any future HPL programs.

'In our review of our process and of this participant, we discovered that we failed to complete a background check as required by our own guidelines. We deeply regret this oversight and the concern this may cause our customers. We realize this is a serious matter.

'Every program sponsored by HPL is supervised by HPL staff, and all children are accompanied by a parent and/or guardian. No participant is ever alone with children, and we have not received any complaints about any inappropriate behavior by participants at storytimes.

'We are taking the appropriate action to ensure that the status of every participant in every program throughout our system is verified. We will continue to review our process to ensure that this cannot happen again.

'Once again, we apologize for our failure to adhere to our own process in this matter and to the hundreds of parents and caregivers who have enjoyed this program with their children.'
