U.S. Army soldiers on Vice President Pence's communications team were reassigned for violating curfew regulations in Panama, NBC News reported.

Three U.S. defense officials told NBC the soldiers - who were senior Army members according to one official - had brought women back to their hotel rooms and didn't register the women when they brought them into the building.

Karen Brazell, chief of staff to the White House Military Office, told the Washington Free Beacon earlier this week that "no evidence of prostitution exists with any of the removed service members."

"Four active-duty military members assigned to the White House Communications Agency, from the Department of Defense, are under investigation for confirmed violations of curfew requirements while deployed to Panama in advance of the Vice President's visit August 17th, 2017," Brazell said in an email to the Beacon.

"All four members were removed from Panama before the vice president arrived and have subsequently been removed from White House Communications Agency duty," Brazell told the publication.

The vice president's staff was alerted to the incident when they saw the soldiers bringing the women into the hotel - a secure area - on security camera video, according to NBC's report. Pence visited Panama earlier this month.

The soldiers were subsequently brought back to the United States and removed from the White House detail.

"We are aware of the incident and it is currently under investigation," Pentagon spokesman Lt. Col. Paul Haverstick told NBC. "We can confirm that the individuals in question have been reassigned back to the Army."
