Tears flowed freely during Glenn's TV program on Monday evening, in which Glenn shared memories about his grandfather --- Edward Lee Janssen --- his greatest family hero and the man Glenn chose to name a line of clothing after.
In a poignant moment, Glenn revealed what dictates his often uncanny fashion choices, including why he always buttons the top button of his collared shirts.
"My grandfather wasn't heroic, he was just an average guy. But he had certain values and principles he didn't waver from," Glenn said. "Little did he imagine that his grandson, 40 years later, would still button his top collar button because he wanted to remember his grandfather every day."
Glenn's daughter, Hannah, and son-in-law, Tim, who run the 1791 clothing brand, also joined the program. Hannah became emotional while sharing the reason she won't be able to honor her father in the same way Glenn has honored his grandfather.
"We'll have to find a different way to remember you, because conservative politics are not always welcomed in fashion," Hannah said.
