Gregg top choice, Obama source says

WASHINGTON (CNN) - Republican Sen. Judd Gregg of New Hampshire is the leading candidate to become President Barack Obama's commerce secretary and a decision could come as soon as Monday, an administration official told CNN Saturday.

Gregg said in a written statement Friday that he was among those being considered for the post, but White House Press Secretary Robert Gibbs said Friday that "a final decision had not been made."

"I know that's something that [President Obama] hopes to make a decision on and announce shortly. But until the President tells me to make a personnel announcement from this podium, I'll refrain from getting into individual names on that," Gibbs said at Friday's press briefing.

The administration official spoke on the condition of anonymity because the official was not authorized to discuss administration deliberations.
