Public radio commentator Sandra Tsing Loh, who was unexpectedly fired from Santa Monica station KCRW last month after uttering an expletive in a prerecorded commentary, has landed across town at Los Angeles’s KPCC. The hiring is something of a coup for KPCC, which is owned by Minnesota Public Radio, and which has been aggressively competing for a share of KCRW’s L.A. audience since its purchase. KCRW had offered to rehire Loh after a wave of bad publicity, but she declined to return.
