Rep. Luis V. Gutierrez, D-Illinois, spoke on the House floor Thursday about the woman who was harassed for wearing a Puerto Rican flag shirt in Caldwell Woods last month.
Mr Trybus faces a bail hearing on Friday on two counts of felony hate crime.
The man who was tormenting Irizarry, identified by police as Timothy Trybus, 62, has been charged with assault and disorderly conduct.
Irizzary then begins to talk to her Facebook Live viewers, saying: 'As you can see the police are not even, he's not even grabbing him'.
The officer, Patrick Connor, did not come to the woman's aid or defuse the situation, drawing ire on social media for his inaction.
"You should not be wearing that in the United States of America", he tells her.
"If the investigation confirms the officer did not take appropriate steps to ensure public safety, disciplinary action will be swift", Forest Preserves spokeswoman Stacina Stagner told ABC News via email earlier this week.
I showed my official ID as a Member of Congress, to which the officer said, "I don't think so", indicating that she thought my ID was a fake and that I couldn't possibly be a Member of Congress.
He was first charged with the misdemeanor after he was caught on camera accosting Mia Irizarry at a Cooks County Forest Preserve picnic area in June.
The Forest Preserves of Cook County confirmed that Officer Patrick Connor no longer works for the department following an incident filmed on June 14, which went viral almost a month later. "We can not allow that ugly rhetoric to be the norm in Cook County".
The video shows him approaching her, asking why she is wearing a Puerto Rican flag shirt with the words "Puerto Rico" written below the neckline. She asks the officer for help, saying the man is making her feel uncomfortable. The agency tweeted Monday that an investigation of the officer is ongoing.
A police officer who was filmed standing by as Mia Irizarry, 24, pleaded for his help has quit. "Are you a United States citizen?"
Cook County Board President Toni Preckwinkle called Trybus' behavior "abusive and offensive" and said Connor should have intervened.
Coming closer, the man says: "You're not gonna change us, you know that?"
The female officer then speaks with Irizarry, who gives her version of the incident and the officer explains that they were called to the area after a report that a man was choking a woman. President Woodrow Wilson in 1917 signed into law the Jones-Shafroth Act, granting US citizenship to residents of Puerto Rico.
