Pennsylvania's Republican Senate primary race between Dr. Mehmet Oz and Dave McCormick will head to a recount, the state's elections chief announced Wednesday.
Oz, a celebrity physician and first-time candidate endorsed by former President Donald Trump, led former hedge fund CEO McCormick in the final vote tally by less than half a percentage point, acting Secretary of of State Leigh Chapman's office said.
That narrow margin triggered a mandatory recount under Pennsylvania law.
The recount is estimated to cost more than $1 million in taxpayer funds, Chapman's office said. Pennsylvania counties must begin recounting ballots by no later than June 1, and they must finish their recounts by June 7 at noon ET.
The announcement came more than a week after the primary election. The Pennsylvania Department of State attributed the lag to the fact that the state's laws do not permit "pre-canvassing" of ballots prior to Election Day. That means counties could only start counting mail ballots on the morning of the election, Chapman's office explained last Tuesday.
Her office noted at the time that about 900,000 mail ballot applications were sent in for the primary.
The eventual winner of the Republican primary will compete in the general election against Pennsylvania Lt. Gov. John Fetterman, who was projected to win the state's Democratic Senate primary by a wide margin.
The Senate race in the swing state could prove to be the most pivotal fight of the midterms. Democrats are trying to keep control of the Senate, which is evenly split between 50 Republicans and the 50 senators who caucus with Democrats.
The Pennsylvania seat, which is being vacated by retiring GOP Sen. Pat Toomey, may offer Democrats' best chance to flip a red seat blue.
