WASHINGTON — President Donald Trump left the White House for an unannounced trip Wednesday afternoon to honor the return of a fallen U.S. Navy SEAL.

According to the White House, President Trump and his daughter Ivanka boarded the Marine One around 3 p.m., and departed from the South Lawn.

The president and first daughter arrived at Delaware’s Dover Air Force Base as the remains of Chief Special Warfare Operator William “Ryan” Owens returned to the United States.

Owens was killed during a raid against al-Qaida in Yemen. Thirty people were killed, including 14 militants in the attack.

The Illinois resident is the first known U.S. military combat casualty since President Trump took office.

This is not the first time President Trump has departed from the White House pool of reporters.

Shortly after he was elected, Trump went to dinner with his family at the 21 Club. Journalists only knew Trump was leaving when they saw his motorcade arrive at Trump Tower.

The White House requires journalists to stay with the president to deliver his comments in the event of breaking news.
