The Zionist Organization of America has threatened to withdraw from the Heritage Foundation's Esther Project, a program dedicated to combating antisemitism, unless Heritage Foundation President Kevin Roberts publicly apologizes and ends his organization's association with political commentator Tucker Carlson. The ZOA criticized Roberts for defending Carlson, who has made controversial remarks about Christian supporters of Israel and interviewed figures accused of antisemitism and Holocaust denial. The organization warned that continued ties with Carlson would damage the Heritage Foundation's reputation among pro-Israel conservatives and undermine its efforts against antisemitism. The ZOA's statement also highlighted that other participants, including Rabbi Mark Goldfeder, have already resigned from the Esther Project in protest, and called for Roberts to either sever ties with Carlson or step down.
