Meta, Google, Amazon, Microsoft draw Sen. Warren questions about AI tax subsidies

Senate Democrats are seeking information on how artificial intelligence and data center spending by Meta , Amazon , Alphabet and Microsoft has been subsidized by tax breaks authorized in the 2025 tax cutting and spending package passed by Republicans at the behest of President Donald Trump . Sen. Elizabeth Warren , D-Mass., led the letters, which were sent Sunday night and shared exclusively with CNBC, to the CEOs of the four companies asking for information on tax deductions they've claimed related to AI and data center development and on their lobbying efforts in the lead-up to the passage of the 2025 legislation, known more commonly as the "one big beautiful bill" act . Sens. Tina Smith , D-Minn., and Jeff Merkley , D-Ore., joined the letters.
