Angelo Carusone is an American nonprofit executive and author who serves as president and CEO of Media Matters for America, a progressive watchdog group founded in 2004 that monitors and critiques conservative media outlets for misinformation, bias, and disinformation. He has held the presidency since 2017, expanding the organization's influence through research-driven campaigns focused on countering right-wing narratives from outlets like Fox News and The Daily Wire. Carusone has been instrumental in high-profile initiatives including the 'StopBeck' campaign in 2010, which contributed to Glenn Beck's departure from Fox News through advertiser pressure, and the 'Dump Trump' effort during the 2016 election cycle. His career in progressive activism began earlier with involvement in various causes during and after college. Under his leadership, Media Matters has grown its digital presence and research capabilities while building coalitions with advertisers to pressure conservative media outlets. While praised by progressives for holding media accountable, Carusone and his organization have faced criticism from conservatives who accuse them of partisan bias. He has written on media and politics and advised on political strategies, positioning himself as a key figure in liberal media watchdog efforts.
