An anti-fascist protester who was filmed harassing a woman claiming to be the widow of an NYPD cop killed in 9/11 earlier this month has been identified by the charity he worked for in a scathing statement announcing his firing.

Steve Wilson was caught on camera cursing at the woman and telling her that her husband deserved to 'rot in the grave' at the Patriot Prayer protest in Portland, Oregon, on October 13.

He started by calling her a 'f****** snarky little idiot' because she was standing in front of him and he thought she was blocking him from walking across the street.

When the woman told him her husband died in 9/11, he said: 'Good for him.'

He carried on his tirade afterwards, labeling all NYPD cops 'sodomizing f****** immigrants' and saying: 'Your f****** husband should probably should f***** rot in the grave'.

Steve Wilson is the antifascist protester who was filmed harassing a woman claiming to be an 9/11 widow at a Portland protest earlier this month

The woman has not been publicly named. Oregon Live reports that she may not be an NYPD widow and that there is no proof she was ever married to anyone who died in 9/11.

The newspaper did not name her but said they found no record of her ever living on the East Coast much less being married to anyone who died in 9/11.

As the video spread online last week, Wilson's identity remained a mystery.

A professional skateboarder who bears a striking resemblance to him was wrongly named as the person in the video and he had to fight to clear his name.

On Tuesday, Self Enhancement Inc, a non-profit organization supporting African-American youths, confirmed it was Wilson by announcing he had been fired over it.

'Steve Wilson is no longer an employee of SEI. His behavior does not represent the values of our organization or the high expectations we have for our employees,' the company said in a Twitter statement.

The woman was standing in front of Wilson when he stared cursing at her, saying: 'Now you're going to block me? You f****** snarky little idiot?'

When the woman turned around and pointed to her hat, saying, 'my husband died in 9/11', Wilson shot back: 'Good. Good for him.'

The video shows Wilson curse at the woman as she stood in front of him at a traffic crossing.

'You're going to block me now? You're a f****** snarky little idiot shut the f*** up,' he said.

She said she was merely obeying 'traffic signals' and goaded him: 'Try something, b****' when he started to curse at her.

He shot back: 'I'm not. I'm not going to punch you. I'm not like your husband, I'm not going to hit you.'

She replied: 'I'm not married'.

Wilson posted in the past about his hatred of the police. He has said nothing publicly since the video emerged

Without missing a beat, he carried on: 'I'm not like your f**** cop boyfriend who's going to knock you out.'

The woman then turned around, pointed to her NYPD hat and said: 'My husband died in 9/11.'

Oregon Live reported that the woman, who they did not name, has no history of ever living in New York or being married to anyone who died in 9/11

Wilson, completely unperturbed by her remark, carried on: 'Good for him. Good.'

As they crossed the street, his abuse continued.

'NYPD are a bunch of f***** sodomized... f****** sodomizing immigrants with their bully sticks. So yeah, your f****** husband should probably should f***** rot in the grave,' he said.

The footage spread like wildfire online.

At first, professional skateboarder Charlie Wilkins, who bears a striking resemblance to Wilson was publicly mistaken for him. He spoke out to insist it was not him in the video and that he was appalled by it.

Wilson did not respond to DailyMail.com's inquiries on Tuesday morning.
