Democratic senator Jeanne Shaheen’s aides quietly drafted legislation that would gut federal antitrust enforcers’ budget — a move that could benefit some of the lawmaker’s major finance, weapons, and health care industry donors whose industries are facing the prospect of tougher scrutiny from those antitrust regulators.

Some of those donors’ companies have been actively lobbying Congress on antitrust issues in the lead-up to Shaheen’s proposed cut, according to federal disclosures reviewed by the Lever.

Shaheen aides slipped the budget-cutting provision into a must-pass 1,050-page bill to keep the government open. The language would strip the Justice Department’s Antitrust Division of nearly $50 million, or roughly 18 percent of its resources.
