Rabbis want Israeli hotels to ban Christmas trees because, apparently, they're a threat to the jewish identity:
Jerusalem rabbis instruct hotels to drop Christmas trees
the rabbi of the Technion Institute of Technology in Haifa forbade students to enter the student union building due to a Christmas tree placed there. (…) Rabbi Elad Dokow, writing on the Srugim website, described the tree as an attack on Jewish identity.
Meanwhile, rabbis from the extremist Chabad-Lubavitch sect have Hanukkah parties in the White House:
The White House Hanukkah Party is an annual reception held at the White House and hosted by the U.S. President and First Lady to recognize and celebrate the Jewish festival of Hanukkah. The tradition was established in 2001, during the administration of George W. Bush. The guest list includes hundreds of American Jewish politicians, organization heads, and school and yeshiva deans.
