 The illness comes at a crucial time for the 81-year-old Biden, who has been losing ground in battleground states against Donald Trump. Marsha Espinosa is a Homeland Security official in the Biden administration. I have no doubt he'll be back out there in another creative way. Look, he's resilient both personally and politically. He's been that way all his life. So I think that we can expect to see him pop up on a screen soon.
