President Donald Trump said Friday he didn't know "anything" about what the New York Times reported was a classified 2019 SEAL Team 6 mission in North Korea in which unarmed North Korean civilians were killed during an aborted operation.

The purported 2019 effort would prove an intelligence failure, but the White House and Pentagon have rarely discussed SEAL Team 6 operations publicly.

For the operation, the military chose SEAL Team 6’s Red Squadron — the same unit that killed Osama bin Laden. The SEALs rehearsed for months, aware that every move needed to be perfect. But when they reached what they thought was a deserted shore that night, wearing black wet suits and night-vision goggles, the mission swiftly unraveled.
