Federal prosecutors on Monday are expected to raise concerns over Rod Blagojevich's slotted appearance on Donald Trump's reality show: "Celebrity Apprentice."
At issue is the March airing of the show, which is just months before jury seating is to begin in the former governor's criminal trial, sources said.
The corruption trial is set to begin in June.
Since his December arrest, Blagojevich has embarked on a media bonanza, including releasing a personal memoir and going on a coast-to-coast book tour. Blagojevich has appeared on the "Daily Show," David Letterman and Jimmy Kimmel, to name a few.
So why the concern now?
"Celebrity Apprentice" doesn't air until next spring, so prosecutors are likely complain there's a possibility of tainting the jury pool, sources said. Blagojevich will reportedly join Cyndi Lauper and Sharon Osbourne, among others.
The matter will be before U.S. District Judge James Zagel, who denied Blagojevich's bid to travel to Costa Rica earlier this year. Blagojevich wasn't allowed to travel out of the country. Zagel also encouraged Blagojevich to instead focus on his criminal trial.
Patti Blagojevich took her husband's spot on the show instead.
Blagojevich, who is being paid to be a contestant on Trump's NBC show, has been in New York this week to begin filming the reality series.
A U.S. Attorney spokesman had no comment.
