BIG RAPIDS, Mich. -- Republican vice presidential nominee Sen. JD Vance stepped on stage in Big Rapids, Michigan, on Tuesday and spoke behind a bulletproof glass during his remarks outside -- the first time he's done so at his own campaign event.

       It's similar to the new safety measures in place for former President Donald Trump's outdoor rallies following his assassination attempt in Butler, Pennsylvania, in July.

       Vance did have bulletproof glass in Asheboro, North Carolina, last week, but that was a joint event with the former president.

       Speaking on the economy and jobs at a farm in Michigan, Vance began speaking about the Labor Department overstating its monthly job growth and then accused the Biden-Harris administration of inflating its job numbers to cover up the economy's problems.

       "Now, last week, the biggest heist in American history happened right under Kamala Harris' nose," Vance claimed. "Somebody stole 818,000 jobs that she and Tim Walz had been bragging about. Did y'all see that? Where did they go?"

       He accused the administration of "cooking the books to hide how bad the economy really is under Kamala Harris."

       When discussing Harris' record, Vance claimed that Harris doesn't know what she believes.

       "In some ways, I feel bad for Kamala Harris," he said. "... But I'm not sure that this is a woman who knows what she actually believes."

       Harris, who laid out her economic agenda earlier this month, is still working to define her stances on several key voter issues. The vice president has already distanced herself from some of her former positions laid out in her 2020 presidential bid.

       Vance referred back to Harris' remarks at the Democratic National Convention last week, where she said there would be "consequences" putting Trump back into the Oval Office, asking "is she the vice president or the vice principal?"

       Later, speaking to reporters, Vance said those Harris comments don't resonate with Americans.

       "I don't think that's persuasive to most Americans and warning them about voting for the wrong person is just, I think it's ridiculous," Vance said.
