A freelance broadcaster who works for music and documentary programs has been fired from a job after public radio network NPR questioned her involvement in a Washington protest.

Lisa Simeone said Thursday that she was fired from "Soundprint," a documentary show that isn't produced by NPR but is aired by an NPR affiliate. Simeone says she was fired Wednesday in a phone call during which NPR's code of ethics was read to her.

Simeone also hosts "World of Opera," a show produced by WDAV, a North Carolina-based music and arts station. The program is distributed by NPR.

NPR issued a statement on its website saying it's in "conversations with WDAV about how they intend to handle this."

Simeone says she's involved with protesters who have been using the slogan October 2011/Stop the Machine.
