1789 Capital, the venture capital firm with Donald Trump Jr. as a partner, rejected a congressional inquiry led by Rep. Jamie Raskin and declined to provide confidential business records. Raskin, the ranking Democrat on the House Judiciary Committee, is examining whether political ties or proximity to the Trump administration influenced outcomes for portfolio companies including Anduril Industries, Juul, Polymarket and Vulcan Elements. The committee sought portfolio data, government communications, due-diligence files and records related to Trump Jr.’s hiring, as well as preservation of messages sent through Signal, WhatsApp, Telegram and X. The firm’s lawyers Alexander J. Merton and William A. Burck called the inquiry political gamesmanship and disputed Raskin’s characterization of its investments. The inquiry highlights Juul’s March 2025 investment and subsequent FDA marketing clearance, Polymarket’s valuation increase from $300 million to $15 billion after a federal operating license and 1789’s investment, and Vulcan’s rise from about $200 million to roughly $2 billion after a $620 million Defense Department loan commitment. The firm says Vulcan had federal business before 1789’s financing round and that it was one of several institutional backers. Democrats lack subpoena power without majority control of the House.
