Biden says he won't testify in impeachment proceedings

IOWA FALLS, Iowa — Joe Biden said that he will not testify in impeachment proceedings against President Trump, a rebuke to Republican lawmakers who say that they want to hear from him.

“No, I’m not going to let them take their eye off the ball,” Biden said Wednesday when asked if he would appear voluntarily. “The president is the one who has committed impeachable crimes. I’m not going to let him diverge from that. I’m not going to let anyone diverge from that.”
