Clyburn says he’ll make his endorsement at 11 a.m. Tuesday.

“I voted,” he told the Stamford Advocate. “I’m not undecided, just unpledged.”

Clyburn will likely endorse Barack Obama. But instead of being framed as the leading black man in the Congress endorsing what could be the first black president, the endorsement will likely be looked at as a response to the mismanaged statements that have flown out of the Clinton camp in regards to race and civil rights in this primary.

Also: Clyburn won’t be the only endorsement Tuesday.
