 ABC's Rachel Scott has the congressional reaction. One Democratic senator telling me that the president is clear-eyed about the demands of the presidency, the urgency of the moment, and the importance of defeating Donald Trump. But others say that they still have concerns, that the dam hasn't broken, but the bleeding has not stopped either. Another Democrat telling me, better but not sure that it's enough, that they need more than one interview, more than 22 minutes to prove that the president has the stamina to continue in this race and defeat Donald Trump.
