Vice-president dismisses opponents' attacks that president is too old to seek out a second term and says he's going to be fine'

Kamala Harris on Sunday declared herself ready to assume the presidency if it ever behooved her to do so - but she also made it a point to dismiss opponents' political attacks that Joe Biden is too old to seek out a second term in the Oval Office.

Asked on CBS's Face the Nation whether she was prepared to serve as commander-in-chief in case Biden became unable to carry out his duties, Harris said: Yes, I am, if necessary."
