The Cumberland County Sheriff’s Office in North Carolina announced Wednesday that it disciplined five officers for failing to follow "professional standards" during a March 9 rally for Republican frontrunner Donald Trump.

Three deputies were demoted in rank and were suspended without pay for a period of five days. Two other deputies were suspended for three days without pay, but were not demoted in rank, Sheriff Earl "Moose" Butler said in a statement.

Butler said all five of the deputies are facing disciplinary action "for unsatisfactory performance and the failure to discharge their duties." Each will be placed in a probationary status for the next year.

The March 9 rally for the billionaire businessman was interrupted by protesters, one of whom was punched in the face. In a video of the assault, it appears some of the officers saw and ignored the violence against the protester, who was later identified as Rakeem Jones.

Butler launched an investigation into the incident shortly after the video began circulating online.

"The actions of the deputies, and their failures to act in situations such as that which occurred during the Trump rally at the Crown Coliseum, have never been and will not ever be tolerated under the policies of this office," Butler said in the statement.

Butler added that the officers' previous conduct was a factor he considered when dolling out punishments, perhaps explaining the discrepancy in disciplinary action between the five officers.

Trump has repeatedly said in media interviews that he does not condone violence, although those statements seem to be at odds with statements he has actually made at rallies. At a Las Vegas event in February, Trump lamented that "we're not allowed to punch back anymore" and reminisced about the "old days," when a protester could "be carried out on a stretcher." There have been several other similar instances.

The Republican frontrunner has also said he'd "look into" paying the legal fees of John McGraw, a 78-year-old man who was later charged with assault and disorderly conduct after attacking Jones at the North Carolina protest.

The sheriff's office decided against charging Trump with inciting a riot after the office's investigation into the North Carolina rally didn't turn up enough evidence to do so.
