"Have you seen what Mitch McConnell said? He told me he wasn't going to get a single vote in order to allow me to get, with the help of everybody here, that $1.9 trillion ... program for economic growth," he said. "Look it up, man. He's bragging about it in Kentucky."
"It's a great thing for Kentucky, it's getting $4 billion to help poor -- it's amazing," Biden added, mimicking McConnell and gesturing widely.
