Loved ones bid their farewells Saturday at a private funeral for Army Sgt. La David Johnson, one of four US soldiers killed in Niger, whose death has been at the center of a public dispute this week between President Donald Trump and a congresswoman.

Army Sgt. La David Johnson's burial was held in Cooper City, Florida. Johnson and three other US servicemembers were killed in an ISIS ambush in Niger.

Sgt. La David Johnson was found nearly a mile away from the central scene of the ambush in Niger that killed four US soldiers -- including Johnson -- and wounded two others, four administration officials familiar with the early assessment of what happened told CNN on Friday.

Details related to the deadly military breakdown in Niger remain murky two weeks after the incident as investigators work to determine precisely what happened. CNN's Jim Sciutto reports.
