Donald Trump and Mike Pence will make dubious history this weekend when they make a joint appearance at the annual Values Voter Summit, an event hosted by the anti-LGBTQ hate group the Family Research Council. It will be the first time members of a major political party’s presidential ticket will appear at the event in person. Mitt Romney was the first candidate to address the gathering, but he did so via a prerecorded video message.

The event will be a real who’s who of the hateful. Other speaks will include Michelle Bachmann, Rick Santorum, Focus on the Family’s James Dobson, Kirk Cameron, Reince Priebus and “Duck Dynasty” reality star Phil Robertson.

That means Trump and Pence will share stage time with members of the extreme right who have compared homosexuality to pedophilia, denigrated LGBTQ service members, and have defended laws criminalizing homosexuality, both at home and abroad, as Right Wing Watch points out.

Trump is scheduled to speak on Friday, Sept. 9, the first day of the three-day conference.

“As the 2016 presidential election approaches, there is a growing realization among voters that the future of our freedoms and even our identity as Americans hangs in the balance,” said Family Research Council Action President Tony Perkins in a statement on Wednesday. “I am certain that Donald Trump and Mike Pence will underscore not only the importance of this election, but the important role conservative Christian voters have in influencing the outcome of the November election. The fact that this is the first GOP presidential ticket to attend since the Summit’s inception in 2006, demonstrates an understanding of the importance of values voters in the general election and a desire to work with them in addressing the critical issues facing our nation.”
