Cahill on the Hill — Top Investigation Developments — August 2026
September 18, 2026
Cahill’s Congressional Investigations practice has published the first installment of Cahill on the Hill, a new monthly series examining key developments in congressional investigative activity. Partners Edward O’Callaghan, James Mandolfo, and Sean Tonolli highlight where congressional oversight is focused, the industries and individuals drawing scrutiny, and the practical considerations for those engaging with congressional investigators.
The August 2026 edition covers:
1. Prediction Markets Under the Microscope: Bipartisan scrutiny of prediction market platforms continues, with Democratic senators urging the CFTC to increase oversight of wildfire-related event contracts and the House Oversight Committee investigating potential insider trading on platforms such as Polymarket and Kalshi.
2. Wall Street's Ties to Jeffrey Epstein: Senate Finance Committee Ranking Member Ron Wyden released a report examining alleged ties between Wall Street banks and Jeffrey Epstein, while the House Oversight Committee pursued subpoenas against Leon Black, former CEO of Apollo Global Management, who has sued to quash them.
3. Dr. Fauci Contempt Proceedings: The Senate Homeland Security Committee passed a resolution to hold Dr. Anthony Fauci in contempt of Congress for invoking the Fifth Amendment, raising novel procedural and legal questions about the enforcement mechanism and the effect of President Biden's prior pardon.
4. Private Sector Ties to the Trump Family: Democratic lawmakers in both chambers continued to probe government contracts awarded to companies with reported ties to President Trump's family, including Vulcan Elements' $620 million loan from the Department of War.
5. Artificial Intelligence Oversight: Scrutiny of AI companies remains a bipartisan priority, with House Democrats calling for hearings with AI CEOs and Senator Josh Hawley expanding his investigation into AI-assisted surveillance cameras.
