Top officials at the biggest police union in the country are upset with Hillary Clinton, saying she snubbed them.

The leader of the National Fraternal Order of Police told The Hill that the Democrat sent a signal through her staff that she wouldn’t be seeking the union’s endorsement.

"It sends a powerful message. To be honest with you, I was disappointed and shocked," said Chuck Canterbury, the president of the National Fraternal Order of Police. "You would think with law enforcement issues so much in the news that even if she had disagreements with our positions, that she would’ve been willing to say that."

Clinton’s GOP presidential opponent, Donald Trump, is now actively seeking the union’s support as he trumpets a “law and order” message on the campaign trail.
