MT. LEBANON (KDKA) — For the third time in the last two days, a Pittsburgh-area congressman or congressional candidate is the victim of vandalism. Congressman Conor Lamb’s Mt. Lebanon office is now the latest.

The front of the office appears to have been sprayed with red paint with the symbol of a hammer and a sickle. The words “Don’t vote! Fight for revolution” also were sprayed on the front of the building.

In a statement posted on Twitter, Conor Lamb said: “Our office is open today. A little spray paint isn’t going to keep us from being there for you.”

Mt. Lebanon police say they are investigating. They couldn’t get into specific details but cameras are outside the office. It’s unclear when the vandalism took place.

Lamb’s opponent in the congressional race, Sean Parnell, had his house vandalized sometime overnight Saturday into Sunday. It was a similar message in red spray paint.

“There is an election coming up. Things are hyper partisan. This type of behavior isn’t acceptable on either side of the aisle,” Parnell said.

According to Parnell, Ohio Township Police are investigating the vandalism.

“Send a message at the ballot box if you’re unhappy with me or what I stand for. But don’t come to my home and vandalize my home,” Parnell said.

Congressman Mike Doyle discovered Sunday morning his South Side office office was vandalized with the same message in red spray paint.

His office released a statement saying, “The overwhelming majority of Americans wholeheartedly support free and fair elections, which are the foundation of our democratic government. Vandalism by a few self-described revolutionaries will never change that.”

Pittsburgh Police said it is investigating that act of vandalism.
