Rep. Lauren Boebert and her boyfriend Kyle Pearcy, a real estate broker from Windsor, Colo., attended a Halloween party in Loveland, Colo., on Friday night, in costumes portraying a Mexican woman and an Immigration and Customs enforcement agent, photos obtained by ABC News show.

The congresswoman was dressed in a traditional Mexican dress and wore a sombrero while Pearcy wore an ICE vest over fatigues.

A chalkboard sign that appeared in other photos from a separate public event the couple attended the same night which are widely circulating online was slung on the back of a chair and is out of the frame in the pictures, according to a party guest who spoke to ABC News.

The text on the sign, which appears to be joke mocking the pronunciation of “you see” said “Mexican Word of the day: JUICY. Tell me if Juicy Ice coming.”

“It is the most disgusting thing I have ever seen. Even the conservatives [at the party] were in shock. People avoided them,” a person who attended the party said.

In a statement to ABC News,  Boebert’s office said, “It’s a Halloween costume. Tell our Senators to vote for the CR and open the government. They are choosing to let millions of American families suffer.”
