Earlier Monday, Obama answered questions on Twitter for an hour as the White House sought to keep up the pressure on the issue.
In response to a question about his insistence on higher tax rates for the wealthiest earners, Obama said that "high end tax cuts do (the) least for economic growth & cost almost $1T." By contrast, he said, "extending middle class cuts boosts consumer demand & growth."
Obama said he was open to "smart cuts" in spending, "but not in areas like R&D" and education, which "help growth & jobs." He also said he opposes spending cuts that would hurt the disabled or other vulnerable groups.
