“This is repulsive.”

That was the reaction of senior Clinton operative Ian Sams as parents of American killed by illegal aliens spoke at a Phoenix rally Wednesday night by Republican presidential nominee Donald Trump.

Sams is the battleground states communications person for the campaign of Democratic presidential nominee Hillary Clinton.

“This is repulsive.”

The time stamp of 9:38 p.m. CDT matches when Trump brought what he called “Angel Moms” on stage according to a tweet at around the same time by Reuters reporter Emily Flitter.

Sams wasn’t the only one “repulsed” by the sight of grieving loved ones of Americans killed by illegal aliens being given a platform by Trump.

Mark MacKinnon of the Globe and Mail called the mothers gathered on stage a “hate rally”
