NEW YORK -- CBS says its daytime show “The Talk” will stay on hiatus for another week after a discussion about racism involving co-host Sharon Osbourne went off the rails last week.The network said in a statement that it is committed to “a process where all voices are heard, claims are investigated and appropriate action is taken where necessary.”Osbourne reacted angrily last week during a discussion about British television personality Piers Morgan, who she describes as a friend.
