Former Vice President Joe Biden says Republican Senator John McCain is a fighter. In an interview with NBC News, Biden said the Arizona senator had been his friend for more than 40 years.
He said McCain, who is suffering from the same form of cancer that Biden's son Beau died of in 2015, is doing okay.
The Democratic former V-P said that the two had engaged in rich political fights for decades, but at the end of the day, mutual respect is all that remains.
