Cardano founder Charles Hoskinson warned that cryptocurrency executives who attended a White House crypto summit could face investigations if Democrats regain control of Congress in the 2026 U.S. midterm elections. His remarks came after users mocked him for not being invited to the event, hosted by President Donald Trump last month. Attendees included Coinbase CEO Brian Armstrong, Ripple CEO Brad Garlinghouse, Robinhood CEO Vlad Tenev, Kraken co-CEO Arjun Sethi, Gemini co-founders Tyler and Cameron Winklevoss, and Chainlink co-founder Sergey Nazarov. Hoskinson predicted that half of the crypto executives pictured in the Oval Office could face investigations under an empowered Democratic Party. He linked that assessment to criticism of Trump family-linked crypto ventures, close administration-industry ties, and what he called a poorly managed Republican approach to crypto legislation. The warning is a political assessment, not evidence that specific investigations have been announced or planned. It comes as the Trump administration pursues a more crypto-friendly policy and supports legislation including the CLARITY Act, while companies such as Ripple, Coinbase, and Gemini previously faced enforcement actions during the Biden administration.
