Leading House Democrat Adam Smith calls on Biden to end presidential bid

Ranking Democrat on armed services committee says debate was alarming' and urges president to stand aside

Joe Biden's position among congressional Democrats eroded further on Monday when an influential House committee member lent his voice to calls for him to end his presidential campaign following last month's spectacular debate failure.

Adam Smith, the ranking Democrat on the armed services committee in the House of Representatives, issued the plea just hours after the president emphatically rejected calls for him to step aside in a letter to the party's congressional contingent.
