A flock of pigeons wearing tiny “Make America Great Again” hats was released in Sin City by a group of Trump boosters on the eve of the Democratic debate, according to a report Wednesday.

In the bizarre stunt, activists adorned one of the birds with a coifed Trump wig as part of the “aerial protest,” according to a press release cited by news3lv.com.

“[It took] exhaustive research, logistical hurdles and pigeon care taking,” the organization, Pigeons United To Interfere Now, said in the release.

The political flap comes as six Democratic presidential candidates gear up for a debate on Wednesday at 9 p.m. EST in Las Vegas. They include Sens. Elizabeth Warren (D-Mass.), Amy Klobuchar (D-Minn.) and Bernie Sanders (I-Vt.), former South Bend, Ind., mayor Pete Buttigieg, former vice president Joe Biden, former Big Apple mayor Mike Bloomberg.

The group, which is also known as P.U.T.I.N — and led by a man who goes by “Coo Hand Luke” — said it was inspired by the Cold War-era CIA operation “Tacana,” in which agents used pigeons fitted with tiny cameras to spy on Soviet Union sites.

On Tuesday, President Trump arrived in Vegas and has a campaign rally planned for Friday.

In December, a flock of pigeons wearing cowboy hats was spotted in Las Vegas, and one of the birds later died, possibly from glue fumes. P.U.T.I.N doesn’t say how it got the teensy caps to stay put on the birds heads. It wasn’t immediately clear if that stunt linked to the same group.
