Former President George H.W. Bush is now the longest-living president in U.S. history at the age of 93 years and 166 days.

Bush on Saturday surpassed the previous record held by Gerald Ford, who lived to be 93 years and 165 days old before he died in December 2006.

Ronald Reagan, the third-oldest living president, lived to be 93 and 120 days, 46 days less than H.W. Bush.

The milestone was pointed out on Twitter by Gabe Fleisher, author of the "Wake up to Politics" newsletter.

Last month, he joined the nation's four other living former presidents for a hurricane relief concert in Texas after parts of the state were devastated by Hurricane Harvey. During the ceremony, he was honored by his son, former President George W. Bush.

Later in October, Bush was forced to apologize after several women came forward to allege that he inappropriately touched them during photo opportunities.

In the statement released through a spokesman, the former president acknowledged that he “patted women’s rears in what he intended to be a good-natured manner.”

“To anyone he has offended, President Bush apologizes most sincerely," Bush spokesman Jim McGrath said.
