Democratic Senator John Fetterman has publicly criticised his own party for tolerating a drift towards socialism and communism, singling out figures who have praised Mao Zedong as an influence he considers "foreign to any Democrat". Speaking at the Israel on Campus Coalition conference, the Pennsylvania senator warned that increasingly radical, anti-Israel voices within the party risk pulling it away from mainstream American politics, a message that lands as several openly socialist candidates have recently gained ground in Democratic primaries.

Fetterman specifically criticised the growing prominence of socialist streamer Hasan Piker, saying he would never elevate someone simply because they have a large following on Twitch, and drew a firm line against anyone who identifies with or praises communist figures. His remarks come amid a broader internal Democratic split highlighted in the 2026 midterm primary season, with socialist-aligned candidates winning contests in states such as Michigan even as establishment Democrats have fought back successfully in other races.
