On January 17, 2003 The Associated Press reported that "Sen. Joe Lieberman's strict observance of the Jewish Sabbath may cause minor inconveniences during his bid for the Democratic presidential nomination, but the Connecticut senator and his staff expect it will pose few significant obstacles to waging an aggressive campaign... The bigger challenge for Lieberman in the Democratic contest for president could be addressing such issues as the Middle East, where he wants to develop a position on the region that both Jews and non-Jews see as fair and independent... Lieberman's staffers describe him as "an observant Jew," while others describe his beliefs as "modern Orthodox." Lieberman strictly observes the Jewish Sabbath by refusing to campaign from sundown Friday through sundown Saturday."
