The economy is expected to dominate President Barack Obama’s news conference at 8 p.m. But perhaps the power of his prime time presence can be judged by his ability to change the TV line-up –  the popular “American Idol” has been moved to Wednesday.

NBC’s “Today” show asked White House spokesman Robert Gibbs whether Obama wanted to risk angering the show’s 31 million viewers and, more scary, judge Simon Cowell.

“No I think taking on Simon along with the economy might be one too many things to take on,” Gibbs said with a laugh. 

“But I think it’s important that the president talk to the American people about our economic recovery and we’ll just build up the suspense for American Idol,” he said.

Treasury Secretary Timothy Geithner and Federal Reserve Chairman Ben Bernanke go to OBAMA/Capitol Hill in the morning to appear before a House Financial Services hearing on “Oversight of the Federal Government’s Intervention at American International Group (AIG).”
