CNN anchor Kate Bolduan challenged Democratic Michigan Gov. Gretchen Whitmer on Tuesday regarding Vice President Kamala Harris’s failure to deliver on her campaign promises during her three-and-a-half years in office.

Bolduan referenced comments made by Republican vice presidential candidate J.D. Vance, who told CNN on Friday that Harris is making empty promises to address the issues facing Americans despite having had three-and-a-half years to act on her current campaign commitments.

In response, Whitmer defended Harris, arguing that Vance’s criticisms showed a lack of basic understanding about the role of the vice presidency.

“How do you make the case that you’re gonna get stuff done if you have three-and-a-half years and you haven’t gotten it done? Does [Vance] have a point?” Bolduan asked.

“Oh my gosh, when you look at just even in J.D. Vance’s hometown, a steel mill that is now thriving that was on the precipice of closing under Trump’s last term, it’s thriving now because Harris and Biden worked to make sure we are on shoring supply chains,” Whitmer said. “This is about American manufacturing, and when you look at J.D. Vance’s own state, how much people have benefited [from] good paying jobs … But for J.D. Vance to show how little he knows about the vice presidency, I think is very revealing and is exactly why we need leaders who understand the job and can get stuff done and make our lives better.”

Since her tenure in the U.S. Senate and her unsuccessful 2020 presidential campaign, Vice President Kamala Harris has shifted her stance on several policy issues. As a senator, Harris co-sponsored the Green New Deal in 2019 and supported eliminating the congressional filibuster to facilitate the bill’s passage. Additionally, she advocated for a ban on fracking during her presidential run, a position that her current campaign has since backed away from.
