PITTSBURGH (KDKA) — U.S. Senator Bob Casey is criticizing the Attorney General for his use of the U.S. Attorney’s office in Pittsburgh as part of the Ukraine investigation.

Barr set up a special intake process for U.S. Attorney Scott Brady to vet information from Rudy Giuliani.

Casey said that local resources should not be used for vetting so called “conspiracy theories.”

The U.S. Attorney’s office has declined comment thus far.
