Democrat Abdul El-Sayed has won Michigan’s US Senate race, defeating former Republican lawmaker Mike Rogers and becoming the first Muslim elected to the US Senate, according to US television networks.

“Michigan, we did it!” El-Sayed declared at his victory celebration in Detroit, where hundreds of supporters gathered to celebrate.

“I am so proud and honoured to stand here as your senator-elect from the great state of Michigan,” the 42-year-old said.

El-Sayed secured the victory despite a late campaign setback when Democratic Congresswoman Haley Stevens, whom he defeated in the party primary, endorsed Rogers shortly before election day.

A former medical administrator, El-Sayed campaigned on progressive promises, including universal healthcare, reducing the influence of money in politics and tackling the rising cost of living.

He replaces retiring Democratic Senator Gary Peters and held a lead of nearly six percentage points over Rogers when US networks called the race.

His campaign attracted large crowds across Michigan, including in traditionally Republican areas, while drawing support from labour unions, activists and younger voters.

Republicans had launched a fierce campaign against El-Sayed, portraying him as a radical and questioning his patriotism. He also faced Islamophobic attacks and mockery over his Arabic name from President Donald Trump and Vice President JD Vance.

Addressing Vance during his victory speech, El-Sayed said the vice president was constitutionally obligated to swear him into office in January.

The victory came amid a strong showing by Democrats in several races, prompting jubilant supporters at El-Sayed’s headquarters to chant: “Tsunami! Tsunami!”
