Donald Trump-endorsed candidate, Mehmet Oz has won the Republican primary race for a US Senate seat in Pennsylvania, following a recount.
Wellness celebrity Oz, who will square off against Democrat John Fetterman in a November 8 midterm election, gained a margin of 916 votes, according to Edison Research.
The race is crucial to Republican hopes of regaining control of a Senate now narrowly held by President Joe Biden's fellow Democrats.
"I will do my part to try to unite Republicans and Pennsylvanians behind his candidacy, behind his nomination for the Senate," rival David McCormick said in conceding to Oz.
The former US President has endorsed over 190 candidates in the midterm contests, trying to solidify his status as the Republican Party kingmaker. His picks have not always prevailed.
Trump endorsed Oz in April, after his previous pick in the race dropped out when his estranged wife alleged physical abuse and he lost a battle over custody of his children.
"I look forward to campaigning in every corner of the Commonwealth for the next five months to earn the support of every Pennsylvanian," Oz said on Friday.
Republicans are seeking to regain control of both the House of Representatives and the Senate in November. They are well positioned to regain control of the House, which could enable them to stonewall Biden's legislative agenda.
Democrats have a better chance of keeping their razor-thin Senate majority, but to do so will need to perform well in races including in Pennsylvania.
