'Run against me': Biden makes 3 things clear amid age row

​President Joe Biden started the week with a bang -- first shooting off a letter to Democrats in doubt over his candidacy and then appearing on NBC's Morning Joe where he vigorously stamped out the growing criticism inside the party about his age, health etc. In a contrast to a shaky Biden, the president appeared firm and resolute as he said he does not care about what the elite donors are saying; he knows he can defeat Donald Trump and that's why he is in the race.
