Telemundo reporter "on leave"

Telemundo closes the barn door - after the journalistic integrity gets out.

Spanish-language network Telemundo has placed a newscaster on leave while it investigates whether her romantic relationship with Mayor Antonio Villaraigosa breached journalistic ethics, TV station KVEA said Thursday.

The Telemundo affiliate announced the probe two days after Villaraigosa, whose wife has filed for divorce, acknowledged he had been in an extramarital affair with newswoman Mirthala Salinas for about a year.
