GOP Official Calls for Firing of 'Wine-Swilling' Philly Attorney Involved in Anti-Trump Vandalism The attorney was caught on camera involved in an anti-Trump graffiti incident.

 -- A Philadelphia city attorney is in hot water after he was caught on camera involved in an anti-Trump graffiti incident.

Surveillance video from the early morning hours of Nov. 25 shows two men approaching a Fresh Market in Philadelphia's Germantown neighborhood before one of the men spray-paints an exterior wall. The second man can be seen standing by, with what appears to be a glass of wine in hand, as the first man works. Once he's done, the second man steps back and appears to take photos or videos of the first man's handiwork.

The second man has been identified by First Deputy City Solicitor Craig Straw as Duncan Lloyd, an assistant city solicitor in the law department. Straw said that Lloyd is cooperating with police in the ongoing investigation and that a "course of action" would be determined when more information is available.

"We do not condone this type of behavior from our employees," Straw said in a statement to ABC News.

The other man in the video has not been identified.

Video released by police shows the vandalized wall, which reads "F--- Trump" in black spray paint. Police estimated the damage to cost between $3,000 and $10,000 due to the composition of the stone facade on the wall.

Joe DeFelice, the chairman of the Philadelphia Republican Party, called on city officials to fire Lloyd "immediately" in a statement posted on the party's website titled, "Wine-Swilling, Blazer-Clad, Anti-Trump City Attorney: An Image of Bourgeois America, Enraged."

"The assistant city solicitor in question had ostensibly taken the law into his own hands, since a democratic election didn’t yield his preferred outcome," DeFelice said. "... Did the extra glass of Shiraz give him some sort of delusional confidence that there are no cameras on Germantown Ave? The taxpayers should be entrusting exactly none of our faith into this man. He should be fired from our city’s law department immediately.”

On Thursday, the city's mayor, Jim Kenney, called Lloyd's involvement in the incident a "dumb mistake," according to The Philadelphia Inquirer.

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

Lloyd has been employed with the City of Philadelphia since 2011, according to his LinkedIn page. He did not immediately return ABC News' request for comment.
