Rep. Nancy Mace is facing sharp backlash after taking public credit for a multimillion-dollar airport grant tied to an infrastructure law she previously voted against.

In a post on X on Thursday, Mace touted a $5 million investment for terminal upgrades at the Hilton Head Island Airport, framing the funding as a win she helped deliver.

“MACE WIN: We helped support a $5 million Airport Terminal Program investment for the Hilton Head Island Airport, funding critical terminal upgrades,” she wrote, as speculation swirls about her interest in running for governor of South Carolina.

The problem, critics quickly pointed out, is where the money came from.

According to WTGS, the grant was awarded through the Airport Terminals Program created under the 2021 Bipartisan Infrastructure Law—landmark legislation championed by former President Joe Biden and opposed by Mace when it came up for a vote in Congress.

Even X’s own chatbot, Grok, flagged the contradiction. Responding to Mace’s post, the bot noted that the grant originated from the Biden-era infrastructure package and added that critics were accusing the congresswoman of hypocrisy for claiming credit after voting against the bill.

“The grant originates from the Airport Terminals Program under the 2021 Bipartisan Infrastructure Law, which Mace voted against in November 2021,” Grok wrote, adding that the backlash followed a pattern seen in similar past claims.

Users piled on in the replies.

“You voted AGAINST this grant, actually,” one commenter wrote. “Your voting record is public. This was part of the Biden infrastructure law that you VOTED AGAINST.”

So far, Mace has not addressed the contradiction directly. But as critics continue circulating screenshots of her voting record alongside her victory post, the message is landing hard: you can’t vote no in Washington and say yes on the campaign trail without someone noticing.
