Under President Donald Trump’s second term, the White House press office calls a full lid when the day’s public schedule and expected announcements conclude, typically after Oval Office meetings, executive actions, or briefings end. Recent developments on June 1 included updates to tariffs on steel, aluminum, and copper imports plus Senate nominations and a message on Global Coptic Day, which can extend activity into the evening. Daily factors include the volume of policy meetings, any late-breaking diplomatic or legislative items, and pool reporter updates on whether additional events are planned. Traders watch the official schedule and real-time pool notes, as routine weeks often see lids before 6:30 PM while active policy or international developments push them later.
