 California Democrat Adam Schiff is just one House member raising concerns about President Biden's age and ability to beat Donald Trump. And Schiff has an important race of his own as well. He's facing off against Republican Steve Garvey to be California's next U.S. Senator. But the way Schiff talks, it's almost as if he's focused on another opponent. His opposition to Donald Trump is a large part of his campaign. In fact, he rose to prominence spearheading Trump's first impeachment trial.
