Congressional lawmakers are questioning Meta’s use of $6.6 billion in federal research tax credits as the company expands its AI infrastructure program.

The concern centers on Meta, which is cited in the source as building a $145 billion AI infrastructure program that includes a $27 billion data center campus in Louisiana.

The Louisiana campus is described as one example of that construction program, which lawmakers say may be claiming tax credits intended for cutting-edge research.

The issue was reported by Engineering News-Record, which noted that the tax-credit claims are drawing scrutiny in connection with Meta’s buildout.

The source does not identify a formal response from Meta or detail any change to the company’s construction plans.
