Shillman sits on boards of The
Friends of the Israel Defense Forces, The Jewish Foundation for the Righteous, and the
David Horowitz Freedom Center. In May 2008, President
George W. Bush appointed him to serve on the Honorary Delegation to accompany him to
Jerusalem for the celebration of the 60th anniversary of the
State of Israel. He has funded
Brigitte Gabriel's
ACT for America,
James O'Keefe's
Project Veritas,
FrontPage Magazine and
Rebel News, and has argued against the US accepting Syrian Muslim refugees. He has been described as a
counter-jihad "elite" and high-profile financier. In and around August 2017, he funded several far-right counter-jihad activists who were appointed "Shillman Fellows". Among these fellows were
Laura Loomer,
Raheem Kassam and
Katie Hopkins. In January 2021, it was revealed by
OpenSecrets that Shillman paid nearly $214,000 in 2017 to help Dutch politician
Geert Wilders pay for his successful legal defence in an
indictment for hate speech against Muslims in general and Moroccans in particular. In November 2025 it was revealed that he pulled a $2,000,000 pledge from Turning Point USA due to Charlie Kirk's involvement with Tucker Carlson. ==Philanthropy==
