A White House spokesman said Saturday night that President Trump would make a major statement at 9 am Sunday morning.
Looks like it’s this. According to Newsweek:
The United States military has conducted a special operations raid targeting one of its most high-value targets, Abu Bakr al-Baghdadi, the leader of the Islamic State militant group (ISIS), Newsweek has learned. Donald Trump approved the mission nearly a week before it took place.
Amid reports Saturday of U.S. military helicopters over Syria’s northwestern Idlib province, a senior Pentagon official familiar with the operation and Army official briefed on the matter told Newsweek that Baghdadi was the target of the top-secret operation in the last bastion of the country’s Islamist-dominated opposition, a faction that has clashed with ISIS in recent years. A U.S. Army source briefed on the results of the operation told Newsweek that Baghdadi was killed in the raid. And the Defense Department told the White House they have “high confidence” that the high-value target killed was Baghdadi but further verification is pending.
