Daniella Greenbaum Davis is a writer and social media strategist in New York.President Donald Trump did something extraordinary last week: He called on the nation as a whole to observe a Shabbat. From sundown on Friday, May 15, to nightfall on Saturday, May 16, friends, families and communities of all backgrounds are invited to come together in rest and reflection. He dubbed the event Shabbat 250, as part of the celebration of America’s 250th anniversary and in recognition of Jewish contributions to American life since the nation’s founding.
