Majority Whip Jim Clyburn Endorses Obama Let It Rip!!!

COLUMBIA, S.C. — House Majority Whip Jim Clyburn is endorsing Barack Obama for president.

The South Carolina congressman told The Associated Press on Monday that he has started to phone the state's superdelegates to ask them to get behind one candidate. When asked whether that candidate was Obama, Clyburn said yes.

Clyburn says he'll make a formal endorsement announcement Tuesday.

The backing of the highest-ranking black member of Congress comes more than four months after Obama won the Democratic primary in South Carolina.
