Watch: Biden on American Morning
"I didn't hear the phrase 'middle class.' I didn't hear a single word about health care. I didn't hear a single word about helping people get to college," Biden, a U.S. senator from Delaware, told CNN's "American Morning" Thursday.
He went on to list other policy areas the Alaska governor did not address Wednesday night at the Republican National Convention in Minneapolis, Minnesota.
"They don't have a single answer [for] how to dig us out of the hole we've been dug into the last eight years," Biden added.
