Sen. JD Vance (R-Ohio), former President Donald Trump’s beleagured running mate, attacked Kamala Harris’ new plans to spend hundreds of millions of dollars on the wall on the U.S. border with Mexico — but it didn’t turn out so well.

Vance posted an Axios article Tuesday morning about Harris’ plans for the border should she be elected president on X, formerly Twitter. The article said that Harris would approve a bipartisan border bill that includes money for border wall construction, albeit less than Trump wanted ― even though Harris called the wall a “medieval vanity project” during Trump’s presidency.

That bipartisan bill was proposed after GOP politicians demanded immigration reforms throughout the first part of President Joe Biden’s term. Republicans nixed the package earlier this year after Trump said he didn’t want to give the President a win on the border.

But nuance wasn’t Vance’s concern when he decided to attack Harris for agreeing to fund the wall if elected:

“Kamala Harris is a fake.

If she wants to build the border wall, she could start right now!”

But Congress has to approve funding for projects like the border wall ― they’re not something the president or vice president can simply do by snapping their fingers.

And Vance himself voted against the bipartisan border bill when he had the chance, leading critics online to point out the irony in his post.
