Michael had his wife and children to look after. Under those circumstances, his behavior was impeccable imo. I understand that over the years, he has kept in weekly contact w/his mother, Jane Wyman. Michael was adopted when Wyman and Reagan were married and had lost 2 children after their daughter, Maureen, was born.
I'm not trying to imply anything bad. I was just surprised that, after watching hours of coverage, I never saw Michael Reagan w/ the rest of the family.
Another post mentioned that MR was separated from the rest of the family but I always understood that he visited regularly and was on good terms. Some video on Fox shows he had a deep love for RR.
