Joe Biden dismissed a jab by 2020 Democratic rival Elizabeth Warren about his enthusiasm for trying to enact legislation in a bipartisan manner.

“I read a speech by one of my — good person — one of my opponents, saying that, ‘You know, Biden says we’re going to have to work with Republicans to get stuff passed.’ I thought, ‘Well, OK — how are you going to do it, by executive order?” the former vice president said at a San Francisco fundraiser Thursday, per a pool report.
