From CNN's Carol Costello:
Hit with polls showing low approval ratings, President Obama has recently been kicking up his fiery rhetoric and appealing to his liberal base, who have been frustrated with him for seeming weak in the face of Republican attacks.
The new assertive Obama first appeared during his jobs speech to Congress, when he blasted the rich for not paying their share of taxes. On Saturday, the president delivered another passionate speech before the Congressional Black Caucus.
"I expect all of you to march with me and press on. Take off your bedroom slippers, put on your marching shoes, shake it off, stop complaining, stop grumbling, stop crying," the president said to the CBC. "We are going to press on, we've got work to do."
