BUDAPEST, Hungary (JTA) — Katrina Lantos Swett, daughter of the late California congressman Tom Lantos, called for a “Solidarity Sabbath” to be held in Europe and North America.

Speaking Tuesday at the “Jewish Life and Anti-Semitism” two-day international conference being held in Budapest sponsored by the Tom Lantos Institute, Lantos Swett suggested that during the Solidarity Sabbath, the heads of governments and leaders of states should attend a Sabbath service at a major synagogue in each city “to express solidarity with the Jews and also to join together in opposing hatred and bigotry.”

The special Sabbath will be held in the spring at a date to be named later.

“We join together in deep solidarity to express our rejection of any form of anti-Semitism in our nations,” Lantos Swett, who is the co-chairman of the institute’s executive committee, said, adding that “we will join our voices to send an unmistakable message to those who would tolerate such hatred.”
