(CNN) - Prominent Hillary Clinton backer Charles Rangel thinks the New York senator could have been "far more generous" during her speech Tuesday night after it was clear Barack Obama had clinched the Democratic nomination.
Rangel, the senior member of the New York congressional delegation and an early supporter of Clinton’s presidential campaign, said in an interview Wednesday Clinton should have been more clear about what her future plans are.
"I would agree that after the math was in before her speech, that she could have been far more generous in terms of being more specific and saying that she wants a Democratic victory," Rangel said in an interview on MSNBC.
"I don't see what they're talking about in prolonging this," Rangel added. "There's nothing to prolong if you're not going to take the fight to the convention floor…I don't know why she could not have been more open in terms of doing up front what she intends to do later."
Rangel also said the entire New York congressional delegation is awaiting guidance from Clinton on what to do, and could be put "on the spot" if the New York senator does not explain herself soon.
"We could be on the spot if we don't get some answers about what does it mean when you say that you are not endorsing - or what does it mean when you say that you haven't - you're not out of the race. It just doesn't make any sense. It's inconsistent with wanting a Democratic victory and not endorsing the Democratic candidate."
