With a 90% approval rating from African-Americans, President Obama may not have to worry about losing that base in the next election. But there is some heat coming from congressional black figures.

On a jobs tour in Detroit Monday evening, Rep. Maxine Waters (D-CA) and the CBC addressed a passionate audience in dealing with a very tricky situation for her colleagues.

“We don’t put pressure on the President because y’all love the President,” Waters said. “When you let us know it’s time to let go, we’ll let go.”

“We’re supportive of the President, but we’re getting tired y’all. We want to give the President every opportunity to show what he can do and show what he is prepared to lead on. But our people are hurting. The unemployment is unconscionable. We don’t know what the strategy is. We don’t know why — on this trip he’s on now — he’s not in any black communities. We don’t know that.”
