Casey Anthony, perhaps the most hated mother in America, was spotted among the estimated 3,000 demonstrators who protested President Donald Trump’s executive order barring travelers from seven Muslim-majority countries at Trump’s Mar-a-Lago resort.

WPTV, West Palm Beach, reported Saturday Anthony, the Orlando mother who was tried and acquitted in the 2008 death of her 2-year-old daughter, Caylee, was among those marching the 2.4 miles from Trump Plaza to Palm Beach.

Video of the protest shows Anthony sporting a black cap worn backward and glow-in-the-dark wristbands. She declined to speak on camera but said off camera she opposes Trump’s policies.

Anthony lives in the West Palm Beach area but rarely is seen in public, WPTV said. Radar Online reported Anthony was greeted with cries of “baby killer.”

Anthony was acquitted in 2011 following a six-week trial in the death of her daughter, whose skeletal remains were found wrapped in a blanket inside a trash bag in a wooded area near her parents’ Orlando home by a meter reader.

Caylee had been missing for a month before her disappearance was reported to police. Anthony’s explanation of her daughter’s whereabouts varied. At one point she told detectives the child had been kidnapped by a nanny and that she had been too scared to alert authorities.

She was tried for first-degree murder and prosecutors sought the death penalty.

Defense attorneys argued Caylee had drowned accidentally in the family swimming pool, and her grandfather, George Anthony, had disposed of the body. Though the defense did not present any evidence to back up the theory, it ridiculed the prosecution’s evidence as “fantasy forensics.”

Anthony did not testify.

Though she was acquitted of the murder charge, Anthony was convicted of lying to police. She was credited with time served and freed July 17, 2011.

A private investigator last year said Anthony’s attorney, Jose Baez, claimed she had killed her daughter and hidden the body.

"Baez had told me that Casey had murdered Caylee and dumped the body somewhere and, he needed all the help he could get to find the body before anyone else did,” Dominic Casey told Fox News.
