WATCH: White House says Trump contacts families of slain when authorized

White House press secretary Sarah Huckabee Sanders says President Donald Trump has made as much contact as possible with families of slain military service members.

Sanders said Wednesday that there is a protocol created by the White House Military Office for the president to contact the families.

First, the Department of Defense notifies the next of kin. Then, the Pentagon sends information to the White House, which has to then be re-confirmed. Once done, the president reaches out to the family.

Sanders said Trump has reached out to every family that has been authorized by the military office.

The Associated Press found relatives of four soldiers who died overseas during Trump’s presidency who said they never received calls from him.

Relatives of two soldiers also confirmed they did not get letters.
