General Motors is expected to file for bankruptcy today as part of the Obama administration’s plan to shrink the automaker down to only its more profitable plants, brands, dealerships, and contracts.  A New York dealership started the process early this morning by filing for bankruptcy protection. A wave of other court filings are expected to follow.

GM will move forward with four core brands – Chevrolet, Cadillac, Buick and GMC. The company plans to cut 21,000 employees, about 34 percent of its work force, and reduce the number of dealers by 2,600. GM was announcing plans to close 11 facilities, idle three others and name the buyer of its Hummer division. GM’s stock dropped to its lowest price in company history Friday, closing at just 75 cents. The shares will be virtually worthless in a Chapter 11 reorganization.

Later today Obama will discuss the latest development followed by a news conference with GM President and CEO Fritz Henderson.
