WASHINGTON — The head of U.S. Africa Command will testify before Congress this week as military officials are finalizing their investigation into the deaths of four U.S. soldiers in Niger last fall.

But House Armed Services Committee Chairman Mac Thornberry, R-Texas, said last week not to expect too many new revelations on that ambush during the Tuesday hearing, since Defense Department officials are still reviewing those findings.

The incident made national news last fall not only for the deaths but also because of a lack of public awareness of U.S. military operations in the region and President Donald Trump’s handling of condolence calls to family members of the fallen troops.

The hearing comes amid a slew of defense budget hearings in the House and Senate this week. Thornberry’s committee alone has nine hearings scheduled over three days, after 12 hearings in the two months prior.
