Three days ago the law firm Porter Wright Morris & Arthur filed a lawsuit in Pennsylvania’s federal court on behalf of the Trump campaign who is challenging the election results in the Keystone State. But now days later the law firm has made moves to withdraw from the case.

This is only one of the multiple cases the Trump team has filed in state and federal courts in Pennsylvania alleging widespread voter fraud and irregularities.

In a report from The Hill:

“Plaintiffs and Porter Wright have reached a mutual agreement that Plaintiffs will be best served if Porter Wright withdraws, and current co-counsel and such other counsel as Plaintiffs may choose to engage represent Plaintiffs in this case,” states the memorandum accompanying the motion to withdraw filed Thursday in the U.S. District Court for the Middle District of Pennsylvania.

The motion does not provide an explanation for the decision. It states that Linda Kerns, another lawyer on the case, will remain on representing the Trump campaign.

The New York Times reported earlier this week that there were internal tensions at the firm, which is based in Columbus, Ohio, related to its work for the Trump campaign in Pennsylvania.

In this particular lawsuit, the Trump campaign sued Pennsylvania’s Democratic secretary of state and seven counties on Monday, alleging that the commonwealth implemented an illegal “two-tiered” system in which voters were held to different standards depending on how they cast ballots. The campaign is seeking to prevent the certification of the states’ election results until the case plays out.

Evidence of official ballot observers being turned away has come out in Pennsylvania. The state was previously called for President-elect Joe Biden but President Trump has yet to concede the race.
