Subpoenas for a top Pennsylvania Republican lawmaker’s “forensic investigation” of the 2020 election appear to be on the horizon.

On Friday, state Sen. Doug Mastriano, chairman of the Intergovernmental Operations Committee who sent letters earlier this month to three counties seeking information and materials related to the 2020 election and 2021 primary, said the trio would want “legal cover” if they comply with his request for the audit, to which Democratic officials in the state have voiced opposition.
