According to PoliticoPro, Bartos raised that amount in the 10 days following his announcement. Bartos had reportedly finished the first quarter with $341,355 cash on hand, though there are no filings with the Federal Elections Commission since he had not officially declared for the race.
Bartos announced his bid in a video released April 24th.
The announcement of his fundraising comes as Congressman Lou Barletta (R-Luzerne) is considering a bid for the Senate after President Donald Trump spoke with him about it. State Representatives Rick Saccone (R-Allegheny) and Jim Christiana (R-Beaver), and RNC Delegate Andrew Schektor have all announced bids for Senate. Southeast businessman Paul Addis is also considering a run.
