More info about Daniel Lapin from Wikipedia:
Daniel Lapin (born 1950?) is a political commentator and American Orthodox rabbi living in Mercer Island, Washington, and the founder of Toward Tradition (a conservative Jewish-Christian organization). He also once headed the Pacific Jewish Center in Venice, Los Angeles, California,(as well as the Commonwealth Loan Company and the Cascadia Business Institute). Lapin is co-chair of the conservative American Alliance of Jews and Christians.
Lapin founded the Pacific Jewish Center, a synagogue in Venice, California that views itself as functioning as part of the recent Baal teshuva movement, encouraging Conservative and Reform Jews to adopt and return to a more observant traditional Judaism.
Michael Medved was a member and is currently a board member of Toward Tradition. Actors Barbra Streisand and Richard Dreyfuss, although not politically conservative, participated in that religious community and synagogue. Lapin’s teachings are also aligned with Modern Orthodox Judaism, in that while he promotes observant Judaism, he is strongly in favor of observant Jews having interaction with other faith communities (in his view, mostly conservative and observant Christian communities) and broader political action outside of Judaism. This has placed him at odds with some modern Orthodox Rabbis, who do not approve of working with clergy of other religions.
