Washington (CNN) Roberta McCain, John McCain's 106-year-old mother, is expected to attend the services for her son at the Capitol, the National Cathedral and the Naval Academy, according to McCain aides.

She is expected to attend the formal ceremony at the US Capitol honoring her son's life and service to the nation on Friday morning. The late senator will lie in state at the US Capitol.

Roberta McCain is also expected to attend McCain's memorial service at the National Cathedral in Washington Saturday, where former Presidents Barack Obama and George W. Bush will deliver eulogies, as well as a private memorial service for her son at the US Naval Academy in Annapolis, Maryland, on Sunday.

The McCain matriarch was a frequent presence on the campaign trail when her son sought the presidency in 2008. A spirited woman, even in her advanced age, Roberta McCain has consistently traveled, including taking a trip to Europe in her 90s.

"Do you want me to sit around and play bridge every day? Or discuss my last knee replacement? Or pass around pictures of my grandchildren?" she told CBS News in a 2008 interview alongside her son, John. "Well, that isn't my choice of a way to live."
