Progressive candidate Abdul El-Sayed held a narrow lead over moderate Rep. Haley Stevens in Michigan's Democratic U.S. Senate primary as vote counting continued early Wednesday. The closely contested race remained unresolved, with El-Sayed ahead by a slim margin. The primary winner will face Republican Mike Rogers in November's general election.

Speaking on "CBS Mornings," El-Sayed said his campaign is focused on unifying Democrats following the hard-fought primary and defeating Rogers in the fall. "We welcome anybody and everybody who understands that we need a government of the people, by the people and for the people," He said.
