News Roundup: Work Visa Trouble for Piers Morgan, John Glover Returning to 'Smallville' and More

We all know Larry King is stepping down, but if CNN has its way, the legendary newsman will stick around until the end of the year. Why? Because his rumored replacement is having trouble getting a work visa.

Yep, according to the NY Post, Piers Morgan is having difficulties getting a visa so he can fill King's chair. The plan was to have Morgan in place this fall in either October or November, but the visa problems have obviously caused delays. Morgan has a limited work visa for his summer gig as a judge on 'America's Got Talent,' but that would not carryover for him to work year-round for CNN.

CNN has not set an official date for King's last episode, nor have they named Morgan as the replacement.
