New documentary chronicles Iowa's 1970s refugee efforts

Flashback: Millions of people became refugees because of the Vietnam War.

• Ray was the only governor at the time to answer a call to help resettle families, ignoring anger from some Iowans who disagreed.

The intrigue: This documentary includes footage of last year's wedding between Jeffrey Newland — Ray's grandson — and Jasmine Vong, the daughter of Tai Dam refugees.

• "I wouldn't be here if it weren't for your grandpa," an emotional Vong says to Newland in the film.
