Biden returns to White House at short notice amid Israel-Iran tension

US president was to spend weekend in Delaware but on Saturday returned to Washington to consult with national security team

 ...“to consult with his national security team about events in the Middle East” amid heightened tension between Israel and Iran.

 Although no information was given about whether a particular event or piece of intelligence prompted Biden to return suddenly to Washington, having determined earlier that leaving for a weekend in Delaware was all right, the news of the president’s actions gave a clear signal that the US believes the risk of some sort of Iranian attack on Israel has escalated.
