Ryan, who is scheduled to speak to the full convention Tuesday night, didn't take questions but spent several minutes posing for pictures with delegates.
U.S. Rep. Robert Pittenger, a delegate from Charlotte, echoed Ryan's argument.
He said when Trump spoke to GOP lawmakers in Washington recently, the lawmakers gave him polite applause in welcome. By the time he left 45 minutes later, Pittenger said, most were convinced that he backed the full Republican agenda.
