Several law firms with lobbying businesses tied to Capitol Hill reported year-over-year growth in their Q1 lobbying revenue, according to Lobbying Disclosure Act filings on Monday, as law firms saw an influx of fees related to artificial intelligence, tax and regulatory matters.

Brownstein Hyatt Farber Schreck and Akin Gump Strauss Hauer & Feld each reported their largest Q1 on record.
