Rick Perry’s warning to Federal Reserve chairman Ben Bernanke about “treasonous” behavior even managed to ruffle some conservative feathers, but there will be no apologies from the governor of Texas: "I am just passionate about the issue, and we stand by what we said," he told reporters Tuesday. Perry was speaking in Iowa, just 11 miles from President Obama’s own appearance. “[Obama’s] approach is to study these things,” Perry told a crowd. “We know what the problem is. We’re being overtaxed, overregulated and overlitigated.” Obama, meanwhile, when asked about Perry, said candidates have "got to be a little more careful" about what they say.
