Mia Irizarry complained that a man at Caldwell Woods was questioning her citizenship and telling her she shouldn't be wearing the shirt, although Puerto Rico is a USA commonwealth. Puerto Rico is an American territory.
The incident, which appears to have taken place in Cook County, Ill., was filmed last month as a Facebook live video by Mia Irizarry, who was wearing the Puerto Rican flag shirt. He also said, "You're not going to change us".
Turning toward a policeman, who was standing several feet away, Irizarry said, "Officer, I'm renting this area and he's harassing me about this shirt that I'm wearing".
Irizarry asked a park police officer to intervene multiple times, pointing out that the man was harassing her, and that she paid to rent the area he was intruding on. "Are you a United States citizen?"
'The United States of America is a nation that was built and thrives on diversity, ' Rosello continued in a separate tweet.
At one point he asked the woman, "Are you educated?"
When the policeman didn't respond, Irizarry says, "Officer, I feel highly uncomfortable".
"As you can see, the police, he's not even grabbing him", Irizarry says to her viewers.
The agency adds, "The intoxicated individual involved in the incident was arrested and charged with assault and disorderly conduct".
She plans to interview all officers at the scene as well as Irizarry and said the video will be used in future training exercises by the Forest Preserves. As Mia's video went viral, Forest Preserves informed the public that the officer who failed to protect Mia is under investigation and now on desk duty.
About 10 minutes into Irizarry's 36-minute video, more police officers arrive.
During Tuesday's news conference, police officials clarified that the other police officers arrived after Connor called on his radio for assistance.
On Monday, Puerto Rico's Governor Ricardo Rosselo tweeted an angry reaction about the incident. "People have just as much right to be here as you and when you're drunk, you don't belong here".
The officer appears to ignore Irizarry as the man continues to yell insults at the woman. "I am appalled, shocked & disturbed by the officer's behavior", he said.
And, adding a bit of customer relations to help make things right, the county gave Irizarry zoo passes to the Brookfield Zoo, which is owned by the Cook County Forest Preserve District. Although Puerto Ricans are US citizens, they must register in one of the 50 states to vote in presidential elections.
Rossello also tweeted Cook County Board President Toni Preckwinkle, saying he believed she would handle the situation with justice.
"I am very sorry for the experience the young woman had to (endure) and I'm further troubled by the lack of response and action by the initial officer on the scene".
"In this case, a United States citizen questions the citizenship of another U.S. citizen and American law-enforcement just sits back and watches", he said.
