Despite any potential sour grapes over Sen. Judd Gregg's (R-N.H.) abrupt withdrawal as Commerce secretary nominee, President Obama has invited Gregg to the White House to attend an economic summit next week.

Gregg has been invited to attend the administration's Fiscal Responsibility Summit on Monday, according to an announcement from Gregg's office. Other members of Congress have also been invited, according to the announcement; the White House has not released any information about the event.
