The U.S. Senate campaign of Democratic candidate Abdul El-Sayed began airing his first major television advertisement on Tuesday, an introductory piece highlighting his medical background and support for progressive policies.

The 60-second ad, entitled “Chorus,” is his campaign’s first major ad buy. Coupled with an ad from the Fighting for Michigan PAC that is supporting him which began airing last week, El-Sayed has joined his two primary election opponents in earnest on the airwaves.

The ad outlines El-Sayed’s family background, highlighting his parents’ work in the automotive industry, his playing of sports in his youth and education in the healthcare field.

In the ad, supporters tout his work with the city of Detroit’s health department and his work leading the Wayne County Department of Health, Human and Veterans Services. Backers of El-Sayed also say that is a fighter for working class residents.

“This campaign will take on the powerful with three simple ideas: money out of politics, money in your pocket and Medicare for All,” El-Sayed says.

The ad concludes with U.S. Sen. Bernie Sanders, I-Vermont, who has endorsed El-Sayed, saying: “Don’t worry about his name.”

El-Sayed’s appearance on the airwaves comes after several million has been spent in over the past month by Super PACs supporting U.S. Rep. Haley Stevens, D-Birmingham, and millions committed to ads by a Super PAC in support of Sen. Mallory McMorrow, D-Royal Oak, in recent weeks.

Michigan Republican Party senior communications advisor Greg Manz in a statement bashed the ad and called El-Sayed and his policy proposals extreme.

“Abdul El-Sayed’s ad is a desperate attempt to district from a simple fact: his socialized medicine scheme would put Washington, D.C. bureaucrats between patients and their doctors while saddling hardworking Michigan taxpayers with trillions in new costs,” Manz said. “No amount of campaign advertising will shield the reality that Abdul El-Sayed is extreme, dangerous, and lacks the moral clarity to represent Michigan in the U.S. Senate.”
