WASHINGTON (AP) - Sen. Barack Obama is slated to pick up the endorsement of the powerful Teamsters, the second major union endorsement for the Democratic front-runner in a week, union officials told The Associated Press on Wednesday. Obama will meet with Teamster President James P. Hoffa in Austin, Texas, on Wednesday. The endorsement is expected to come soon thereafter, said the officials, speaking on condition of anonymity because of the planned formal announcement.

The Teamsters represent 1.4 million members.
