Former U.N. Ambassador Nikki Haley will be at a rally for Republican Senate candidate Dave McCormick in Warrendale, Pennsylvania, a suburb of Pittsburgh, on Oct. 30, according to Politico.
The Senate race in Pennsylvania is one of the most competitive races this election cycle as McCormick seeks to unseat Sen. Bob Casey (D-PA).
Haley is quite popular among moderate Republicans, capturing more than 150,000 votes during the Pennsylvania Republican primary despite having already dropped out of the race.
