'Irony of all ironies': J.D. Vance's latest attack on Kamala Harris immediately backfires

Sen. J.D. Vance threw an insult at Vice President Kamala Harris Tuesday that almost immediately boomeranged.

Former President Donald Trump's running mate took to X to accuse Harris of "flip-flopping" on her border security policy positions ahead of the presidential election in November — then faced stern reprimand from a fellow Republican.

"Kamala Harris is a fake," wrote Vance. "If she wants to build the border wall, she could start right now!"

Vance shared an Axios report that described Harris' support of a bipartisan border security bill — killed earlier this year by Trump allies who reportedly feared the impact such a solution would have on his reelection campaign — as an about-face.

Harris, as California's representative in the Senate, was one of three senators to oppose a compromise that would provide billions of dollars for then-President Trump's promised border wall in exchange for a Dreamers citizenship policy, Politico reported in 2020.

At the Democratic National Convention last week, Harris promised to revive the dead-on-arrival border security bill that includes $650 million in funding for a border wall, about 4 percent of the $18 billion Trump requested in 2018.

It was this policy position Vance presented as proof that Harris was a "fake" — an argument that did not impress former GOP Rep. Adam Kinzinger (R-IL).

"BREAKING," replied Kinzinger, "In the irony of all ironies, @JDVance calls Kamala Harris 'fake.'"

Vance has also been accused of flip-flopping with his support of Trump — whom he once dubbed "America's Hitler" — and misrepresenting his upbringing for the convenience of his political career, spurring one columnist to dub him the "Hillbilly phony."

Political commentator Keith Olbermann mocked Vance with the fake rumors involving the Ohio senator and common living room furniture.

"You voted against it," Olbermann said, with the addition of an unprintable moniker involving a futon.

Political commentator and Navy veteran Jared Ryan Sears replied with a lengthy rebuke of Vance's analysis that included a basic political lesson about the extent of Harris' power as vice president.

"The Vice President doesn't have the authority to build a wall or to pay for it," he wrote. "Someone running for the position should know that...Just because you want a dictatorship, doesn't mean America is one."
