Seated in the Oval Office on Wednesday, flanked by his vice president and secretary of homeland security, President Trump walked back an administration practice that has separated more than 2,300 children from their parents along the border.

Rachel Osborn knows kids who slept in the immigrant detention centers in Texas that have dominated recent headlines.

"We have kids who will say that was the worst part of their journey," Osborn says. "They were traveling for weeks and the hardest part was being in this freezing cold room where, you know, they were fed a cold sandwich and had a thin blanket to shiver under."

And they had no parent or caregiver to comfort them and make them feel safe.

Just as darkness fell, Capt. Austin S. "Scott" Miller was hunkered down in a building in Mogadishu, Somalia, together with his soldiers from the U.S. Army's elite Delta Force.

It was Oct. 3, 1993, and a Black Hawk helicopter had just been downed by local militants in the battle of Mogadishu, what would become the core of the book and movie Black Hawk Down. Miller was awarded a Bronze Star with a valor device for the nearly day-long battle that left 18 Americans dead and 73 wounded — including Miller.
