WATCH: Trump holds campaign event in Walker, Michigan

WALKER, Michigan — Former President Donald Trump headlined a campaign event at a manufacturing plant in Kent County, a Democratic leaning county in western Michigan surrounded by more conservative rural areas.

Watch Trump’s remarks in the player above.

Trump issued a scathing screed against Harris on immigration, saying “blood is on her hands” as he points to purported data about criminals entering the U.S. illegally.

“What Kamala Harris has done is unforgivable,” he told more than a thousand supporters from the loading dock of a manufacturing plant in Walker, Michigan. “It’s a crime what she did. There’s no greater act of disloyalty than to extinguish the sovereignty of your own nation.”

Trump also repeated his unfounded claims that Democrats are trying to sign noncitizens up to vote, which is a felony. He claimed the only way he will lose the election is if his opponents cheat.

More than 25 minutes into his speech, Trump turned to the intended focus of the event: the economy.

He boasted about plans to cut regulations and offer other benefits to companies that make their products in the U.S. He said he would issue sweeping tariffs on cars and other products built outside the country.

The former president claimed the auto industry is being taken from Americans “like candy from a baby” and will disappear if he doesn’t win. There’s no evidence the auto industry is disappearing. Auto parts jobs have risen under Biden and auto sales were up 2.4 percent in the first half of this year. Foreign automakers already have multiple U.S. factories, mainly in southern states.

Trump also touted his endorsement from Tesla CEO Elon Musk and suggested the billionaire entrepreneur could have a role in his administration.

“We’re going to get Elon Musk to be our cost cutter,” he said. ” I don’t think I can get him full time because he’s a little bit busy, sending rockets up and all the things he does.”
