Siobhan Prigent and a mob of violent leftists attacked an elderly pro-Trump grandfather at the protests Tuesday against President Donald Trump in London.

In the video Siobhan is seen harassing the Trump supporting grandpa, screaming “nazi scum!” over and over in his face and then LAUGH after the man was physically covered in a milkshake and kicked on the ground.

Prigent can be seen laughing and slip away after the man was knocked to the ground.

Now the abusive leftist is fighting to keep her job as a clinical trials coordinator at the University College Hospital.

She never expected to get caught for taking part in the violent leftist mob.

On Tuesday Siobhan was filmed harassing, abusing and screaming “nazi scum!” at the elderly pro-Trump grandpa.

The Daily Mail reported:

An NHS worker has apologised for screaming ‘Nazi scum’ at a Donald Trump supporter who was covered in milkshake at a protest yesterday. Siobhan Prigent took to Twitter to say she was ‘very sorry’ for her behaviour at the demonstration in Parliament Square. Video footage shows Miss Prigent and a number of marchers yelling at the semi-retired grandfather before he is hit with the drink. He tells the angry mob that he is ‘here to stay’ before throwing the empty cup back at them as a female police officer tries to stop it turning into a brawl. Ms Prigent, a clinical trials coordinator for University College Hospital, is seen holding a placard saying: ‘This episode of Black Mirror isn’t funny any more! #NoThanksNazis’. The NHS worker, who is employed by the London hospital as a contractor through her company Vlek Ltd, now faces a battle to hold on to her job. She apologised in a now-deleted tweet: ‘I am very sorry for my behaviour today. I should have protested peacefully & I didn’t, & I regret that. ‘I’ve let myself down & I do understand that fully. There are two sides to every story, but my actions were my own, & that’s on me. Please leave my family & friends out of it.’

The elderly Trump supporter is a grandfather.

The leftists didn’t care. They screamed in his face, knocked him down and kicked him.

The grandfather said that the ‘hardcore lot’ became bitter ‘because they couldn’t answer the questions and the answers I was putting towards them’. He explained that one of his friends had been hit by a milkshake first, and he was hit while helping him. The man also claimed he was kicked in the legs, and attacked with a banner with a stick on the end. The demonstrators also attempted to remove his Make America Great Again hat – which he eventually got back.

Siobhan has since set her Twitter settings to private.
