The U.S. Navy says it is investigating a SEAL unit after it was caught on camera flying a Donald Trump “Make America Great Again” flag from the convoy’s lead vehicle.

A driver shot cell phone video of a military convoy traveling on I-264 on the south side of Louisville, Kentucky on Sunday.

The original source of the video has deleted it from Facebook, but it was captured by Yahoo Canada and made public.

“The convoy were service members assigned to an East Coast-based Naval Special Warfare unit driving vehicles while transiting between two training locations,” Naval Special Warfare Group 2 spokeswoman Lt. Jacqui Maxwell tells ABC News.

“Defense Department and Navy regulations prescribe flags and pennants that may be displayed as well as the manner of display,” she says.

“The flag shown in the video was unauthorized.”

The woman taking the video sped up to capture the scene after the convoy passed her.

“You’ve got to be kidding me,” she could be heard saying, seemingly upset by the display.

Maxwell says after the inquiry is complete, the unit commander will “make a disposition decision as to the appropriate administrative or disciplinary action.”
