Howard Kohr and AIPAC engaged with Yisrael Beiteinu, particularly during its coalition governments with Likud. AIPAC's lobbying efforts often reflected the party's priorities, such as securing U.S. support for Israeli military operations and opposing diplomatic initiatives perceived as unfavorable to Israel. Kohr's consultations with party leaders helped align AIPAC's U.S. advocacy with Yisrael Beiteinu's policy goals.

Paul Singer has provided financial support to organizations and initiatives aligned with Yisrael Beiteinu, an Israeli political party known for its hardline stance on security and opposition to Palestinian statehood. Singer's funding has supported U.S.-based groups that advocate for policies favored by Yisrael Beiteinu, including strong U.S. military aid to Israel and opposition to the Iran nuclear deal. His financial backing has helped amplify the party's influence in U.S. political circles.
