Sen. Elizabeth Warren (D-Mass) said six companies received $83 billion in federal tax breaks last year as millions of Americans struggled with grocery and doctor-visit costs. An Institute on Taxation and Economic Policy report said the companies represented more than 40% of corporate tax breaks tracked in 2025, exceeding the annual discretionary budget of the U.S. Department of Education. Warren also criticized corporate consolidation and urged regulators to block mega-mergers. She has cited UnitedHealth Group Inc. and CVS Health Corp. as examples of vertical integration (combining businesses at different supply-chain stages) and backed the bipartisan Patients Before Monopolies Act.
