NEW YORK — Joie (JOH'-ee) Chen is returning to television as host of the new Al-Jazeera America network's flagship newsmagazine, "America Tonight."

The network, which premieres on Aug. 20, announced the hire on Wednesday. Chen has worked at CBS News and PBS but is best known for a decade spent at CNN. She's been out of television for the past couple of years.

Paul Eedle, Al-Jazeera America's deputy launch manager for programs, called Chen "a strong journalist with a natural, warm presence on screen."

"America Tonight" will air each weeknight, but Al-Jazeera hasn't said exactly when. It is one of the few specific programs announced in advance of the launch.
