She wasn't the only one in the family to share support and personal memories online. Meghan's mother, the senator's wife Cindy McCain, posted a picture from their wedding in May 1980 on her Instagram account.
The caption reads: \"Thank all of you for the wonderful thoughts. @senjohnmccain is doing well. We as a family will face the next hurdle together. One thing I do know is he is the toughest person I know. He is my hero and I love him with all my heart.\"
