Former NYC subway chief wins GOP mayoral primary

Lhota entered the 2013 mayor’s race after winning plaudits for his response to Hurricane Sandy as New York City subway chief. The transit system was shut down during the storm after sustaining widespread damage, however, service was restored in about a week.
