Ron Reagan, Jr., caused some controversy recently with claims he made in his new book that his father, President Ronald Reagan, showed signs of Alzheimer's disease while he was still in office.
Reagan, Jr. and his half-brother Michael Reagan have both written books about their famous father, timed for release near what would have been President Reagan's 100th birthday.
In his book, My Father at 100, Reagan, Jr. suggested his father was showing signs of Alzheimer's as far back as 1984, at the end of his first presidential term.
"There was just something that was off. I couldn't really put my finger on it," Ron Reagan wrote.
"I've seen no evidence that my father (or anyone else) was aware of his medical condition while he was in office," the memoir read. "Had the diagnosis been made in, say 1987, would he have stepped down? I believe he would have."
Michael Reagan told CBN News that while he was initially angry over his brother's claims, he now believes Ron thinks it was mistake to publish them in his memoir.
