Abdul El-Sayed, the Democratic nominee for U.S. Senate in Michigan, said Sunday he has spoken with Barack Obamaand hopes the former president campaigns with him as the party tries to unite after a bitter primary that exposed deep rifts between its progressive and moderate wings.

El-Sayed said his Friday conversation with Obama was “really warm and inspiring.” The candidate did not provide details.

“I was grateful for his advice. It was very warm, very inviting, and I know that he knows the critical role that Michigan is going to play,” El-Sayed told NBC’s “Meet the Press.”

Asked if he would like to see Obama come to Michigan to drum up support for Democrats before the midterm elections in November, El-Sayed said he “really” hoped so and that Obama “knows a lot about winning Michigan” after carrying the state in the 2008 and 2012 presidential races.

An Obama spokesperson confirmed the call.
