Family Research Council leader Tony Perkins, who had long withheld his support from Trump, took the stage at the Quickens Loan Arena to announce that he would vote for Trump and encourage his large following of evangelical Christians to do the same.

"Donald Trump is the nominee of the Republican Party, and I will be voting for Donald Trump in November, and I will urge my fellow Americans to do the same,” Perkins said.

“Donald Trump has committed to upholding and protecting the first freedom and therefore our ability as citizens to unite our nation once again under God,” he continued said. “Let us go forth from here and do that work.”
