Senator Durbin acknowledges his relationship with Clinton was somewhat strained because of his early and outspoken support of then-Senator Barack Obama over her in the 2008 campaign.

“It was a little testy for a little while and that is understandable,” Durbin said. “I had always had a good, close relationship with the Clintons, but I want to do everything I can to help her be elected president.”
