Bill Clinton and Barack Obama remember Senator McCain

Obama used Twitter to write a status on his behalf, and his wife, Michele Obama, to honour John's “political execution” against the United States.

A little bit of us were tested just as John was once tested, or to show the kind of courage he did. John told us what that means. And for that, we are debtors to him”, Obama wrote.

Barack and John competed against each other in the presidential race in 2008.

Even Bill and his wife, Hillary Clinton, issued a joint statement thanking John for his service over the years, sending all their love for his wife and family.
