Rep. Lauren Boebert (R-CO) received significant backlash after photos surfaced of her wearing a Halloween costume that some said was the "most disgusting" one they had ever seen.

Boebert was photographed wearing a Mexican sombrero and traditional dress. She also carried a sign that read "Mexican Word of the Day: Juicy. Tell me if 'Juicy' ICE coming." Boebert's boyfriend was also photographed with her dressed as an ICE agent.

Political observers and analysts heaped criticism on Boebert for the costume.

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

A spokesperson for Boebert's office defended her costume.

"It's a Halloween costume," the spokesperson told ABC News. "Tell our Senators to vote for the CR and open the government. They are choosing to let millions of American families suffer."

“She should be ashamed of herself,” Stacy Suniga, the president of the Latino Coalition of Weld County, Colorado, told the Boulder Daily Camera. “Though I believe she is incapable of any emotion that generates human decency. Her bigotry and ignorance are clearly evident in her chosen apparel this day.”

“Lauren Boebert put more effort into a hateful Halloween party costume than she ever has into serving the people of Colorado’s 4th Congressional District,” Trishia Calvarese, a Democrat running against Boebert, posted on X.
