“We have to unite,” Biden told reporters in Muscatine, six days before the Iowa caucuses. “I’m not going make judgments now. I just think that it depends upon how we treat one another between now and the time we have a nominee.”
Biden has previously promised to support the Democratic nominee, regardless of who it is. At some stops along the campaign trail, Biden has pledged to “work like hell” to help any of his rivals defeat Trump. The Biden campaign said Tuesday afternoon that the former vice president would support the eventual nominee.
