Jordan Serpone, 33, an audience member from Boston, said on Sunday that Chelsea Clinton introduced her mother to Ms. Messing, a vocal Hillary Clinton supporter who was seated nearby.
Mr. Serpone, a Clinton supporter, said spotting Mrs. Clinton was a surprisingly emotional experience for him.
“I was having every emotion I’ve tried to get rid of over the last few weeks,” he said during intermission. He shook her hand but is still filled with frustration over her loss. “She shouldn’t be here. She should be planning her cabinet,” he said.
Hillary Clinton received a standing ovation at “The Color Purple,” a response far warmer than the scattered booing and clapping that greeted Mike Pence at Hamilton: An American Musical.
