Officials in Lancaster County, Pennsylvania, announced Friday they have discovered up to 2,500 fraudulent voter registration applications that were submitted near the deadline as part of a “large scale” paid canvassing operation.

“We are aware of at least two other counties that received similar applications that are currently being investigated,” Adams said, but she declined to name the other counties, telling reporters that those officials should speak to the issue themselves.
It is encouraging to know officials are watchful and catching these possible registration irregularities prior to folks actually voting. From what it says in the article you linked it appears to be a 'get out the vote' drive and it is not linked to any one political party.
"WGAL reported that Lancaster County Commissioner Ray D’Agostino, when asked if the canvassing operation favored a particular political party, responded, “I can say … it does not appear at this point. It doesn’t seem that it’s any one party. In some cases, they’re registering in different parties.”
