 I'm Monica Ricks. The White House is fielding more questions on President Biden's cognitive health amid more calls for him to quit the presidential race. Press Secretary Karine Jean-Pierre.

This was part of a heated exchange with reporters today after the president sent a letter to congressional Democrats. CBS's Scott McFarlane.
