NPR says "Weekend Edition Sunday" host Audie Cornish has been assigned to co-host the popular weekday show "All Things Considered" when Michele Norris temporarily steps down.
NPR announced Wednesday that Cornish will join the weekday show for one year beginning in January. Norris recently stepped down because her husband has joined President Barack Obama's re-election campaign as a senior adviser.
Cornish was named host of "Weekend Edition Sunday" this year. Previously she covered Capitol Hill and the 2008 presidential campaign.
NPR says it will search for a new host to take over the weekend show for 2012 until Cornish returns.
Cornish will co-host "All Things Considered" with Melissa Block and Robert Siegel.
