Senate Primary Elections: In Pennsylvania, Former hedge fund CEO David  McCormick Concedes to Oz

McCormick conceded the Republican primary in Pennsylvania for U.S. Senate to celebrity heart surgeon Dr. Mehmet Oz 

He acknowledged an ongoing statewide recount wouldn't give him enough votes to make up the deficit 

“It’s now clear to me with the recount now largely complete that we have a nominee,” McCormick said at a campaign party at a Pittsburgh hotel 

Already, the national parties are sponsoring attack ads on TV in a presidential battleground state that is still roiled by Trump 

The Associated Press has not declared a winner in the race because an automatic recount is under way 

Before the recount, Oz led McCormick by 972 votes out of 1.34 million votes counted in the May 17 primary 

Rivals made Oz's dual citizenship in Turkey an issue in the race. If elected, Oz would be the nation's first Muslim senator
