When the man again tries to get in her face, her brother arrives and intervenes.
Video emerged this week of the incident on the Northwest Side in which a man threatens, and curses at a woman for wearing a shirt with the Puerto Rican flag at a pavilion she had reserved for a birthday party.
The park location was not identified in the Facebook post, but a Twitter army tracked the location as one of the areas supervised by the Forest Preserves Department of Cook County, which includes Chicago.
Mia Irizarry posted a video of the June 14 incident on Facebook and showed that she was wearing a shirt that looked like the Puerto Rican flag.
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. "You know that right?" the harassing officer added referring to the woman's shirt. "He was looking forward to an opportunity to explain what was happening".
Connor is scheduled to appear at a disciplinary hearing Thursday.
The Forest Preserves added on Wednesday night that it was "further addressing aspects of this incident".
Eventually, a witness calls authorities, more officers arrive and the man is questioned.
Cook County Commissioner Jesús "Chuy" García had called for such charges against Trybus a day earlier. "The intoxicated individual involved in the incident was arrested and charged with assault and disorderly conduct". "We can not allow that ugly rhetoric to be the norm in Cook County".
ABC News has been unable to reach Trybus.
Eileen Figel, the Forest Preserve District's deputy general superintendent, said there "needs to be a clear and appropriate response in these situations".
Rosello said the officer failed to ensure Irizarry safety.
"It's up to each and every one of us to present a better model to demonstrate with our own actions how to treat each other with more respect", he told reporters Thursday.
'Are you educated?' Trybus asks her in the clip.
"You should not be wearing that in the United States of America", he said.
According to a Morning Consult poll, nearly half of Americans do not know that Puerto Ricans are USA citizens.
Then she says: "Officer, I'm renting, I paid for a permit for this area".
"As you can see the police are not even - he's not even grabbing him".
"You never know, you're right", Connor says.
Finally, multiple police cars pull up, responding to a separate incident, and a female officer informs the man he's intoxicated.
She explains that she has rented the picnic area and has a permit to use the space.
"He continued to follow me and I even asked you to step in because I felt uncomfortable".
"If you're drunk, you don't belong here", she is heard telling the man. The officer is visible in the background of the video, standing several yards from the man and the woman, but he does not appear to respond to the woman's requests for help.
A man suddenly yells off camera, "Puerto Rico is an American state!" Although Puerto Ricans are US citizens, they must register in one of the 50 states to vote in presidential elections.
