President Donald Trump made a secret trip Wednesday to Dover Air Force Base, to honor the first U.S. soldier to die fighting for the United States under the new administration.

Trump went to honor Chief Special Warfare Operator William “Ryan” Owens, 36, a Navy SEAL from Peoria, Illinois.

“We killed an estimated 14 [al-Qaida] members, and … we gathered an unbelievable amount of intelligence that will prevent the potential deaths or attacks on American soil.”

Owens died in a Sunday morning raid of a compound operated by Al-Qaida in the Arabian Peninsula, or AQAP. Trump was joined by his daughter, Ivanka Trump, as they met with Owens’ family in Dover.

According to Reuters, the remains of the Navy SEAL were sent to Dover, home to the largest U.S. military mortuary.

The visit was a surprise to the media, which was not informed of the trip. Only a handful of reporters were told, and these reporters accompanied Trump on the condition of secrecy.

The Pentagon reported 14 militants were killed in the raid in al Bayda province of Yemen. According to multiple media reports, one of the dead was the eight-year-old daughter of the late militant Anwar al-Awlaki, who was killed by a 2011 U.S. drone strike.

Trump’s press secretary Sean Spicer told a news conference on Wednesday that the raid was a success.

“Knowing that we killed an estimated 14 AQAP members and that we gathered an unbelievable amount of intelligence that will prevent the potential deaths or attacks on American soil, is something that I think most service members understand, that that’s why they joined the service,” Spicer said at his daily news briefing.
