(LANSING) – Fourth-term U.S. Representative Haley Stevens has launched her run for Michigan’s open U.S. Senate seat.

The announcement came Tuesday with a video focused on the economic crisis caused by President Donald Trump’s volatile tariffs policies. Walking through a lot full of pickup trucks and SUV’s she tries to make the case that she’s the candidate who will protect Michigan’s critical auto industry.

Stevens, a Democrat, is the fourth well-known candidate to join what is quickly becoming one of the nation’s most watched Senate races, with Republicans' 53-47 majority at stake in a battleground state Donald Trump won in November.

Quickly a top possible contender after Democratic Sen. Gary Peters chose not to seek reelection, Stevens will oppose State Senator Mallory McMorrow and former gubernatorial candidate and public health official Abdul El-Sayed in the Democratic primary.

On the Republican side, former U.S. Representative Mike Rogers is trying again after losing to Democrat Elissa Slotkin in the state’s 2024 U.S. Senate race by just 19,000 votes.

Before Congress, Stevens served on the U.S. Treasury's auto task force following the 2008 financial crisis as President Barack Obama's administration bailed out General Motors and Chrysler. She said Trump's taxes on imports are creating another crisis for the Michigan economy, which rides or stalls based on the auto industry's condition.

Stevens has been an ardent voice from Michigan against Trump’s tariffs, particularly those leveraged against Canada. However, Stevens is among the Democrats who have sought to clarify they are not inherently anti-tariff.
