(USA Today) — President Obama expanded on his fiscal message Wednesday at a virtual town hall meeting at Facebook’s headquarters here. In what felt like a campaign stop, streamed live on the White House’s Facebook page, Obama discussed the budget deficit, fiscal responsibility, investments in technology, health-care reform, the housing crisis and the power of social media. “If we don’t have a serious (plan) to attack the deficit, we will have an even bigger problem” of investors pulling back when the economy starts to perk up, Obama said. “We could slip back into a recession.” “The Republican budget put forward is fairly radical, but I would not call it courageous,” he said. The one-hour event was moderated by Facebook CEO Mark Zuckerberg, who wore a jacket and tie—instead of his customary hoodie. Obama spent as much time talking about raising federal revenue as cutting excessive spending.
