Philadelphia police are investigating an assistant city solicitor in connection with anti-Trump graffiti found on the side of an upscale supermarket in Chestnut Hill

Photographs snapped later show the graffiti to offensive and anti-Donald Trump.

The chairman of the Philadelphia Republican Party, said that Lloyd, pictured, should be fired for his actions.

The city attorney has admitted he made a 'dumb mistake' but has still kept his job according to Philly.com.

'It's still working out. It's certainly hateful and inappropriate and unacceptable...but people are human beings and they make mistakes and it's a dumb mistake,' Philadelphia Mayor Jim Kenney said. 'It's hateful graffiti, hateful graffiti is never acceptable whether it's a city employee or not.'

Lloyd, who makes $63,207-a-year, has worked for the city's Law Department since 2011, representing the city mostly in federal and state discrimination lawsuits.

Mr. Lloyd has already contacted the Philadelphia Police and is cooperating with them. He has kept his job up to now

'We do not condone this type of behavior from our employees,' First Deputy City Solicitor Craig Straw said. 'To my knowledge, Mr. Lloyd has already contacted the Philadelphia police and is cooperating with them. We will decide on a course of action once we obtain more information about the investigation.'

Police have estimated the damage to be between $3,000 and $10,000.

The city's Republican Party have called for Lloyd's to be dismissed.

'If the image of an upper-middle-class city attorney clad in a blazer and sipping wine while vandalizing an upscale grocery store with an anti-Trump message strikes you as perhaps the most bourgeois sight imaginable, that's because it is,' said Joe DeFelice, chairman of the Philadelphia Republican Party to Philly.com.

The video captured the incident which took place just after midnight on November 25

'Did the extra glass of Shiraz give him some sort of delusional confidence that there are no cameras on Germantown Avenue? The taxpayers should be entrusting exactly none of our faith into this man. He should be fired from our city's Law Department immediately.'

Lloyd, 32, attended Germantown Friends School and graduated from the University of Pennsylvania and Temple University's Beasley School of Law, according to his LinkedIn page.

He was identified after police released a video which showing the attorney carrying a wine glass and holding up his cellphone while a second man spray-painted the wall.
