Heavy vehicle movements were seen near the West Wing of the White House as President Donald Trump began his scheduled 11 a.m. intelligence briefing. Eyewitness reports also indicate that General Dan Cain, Chairman of the Joint Chiefs of Staff, is seen leaving the White House. The activity comes against the background of renewed US military planning regarding Iran. Senior US commanders, including Kaine, have recently briefed Trump on possible strikes, as Washington continues to weigh military escalation against diplomatic negotiations.
