Senator Clinton's campaign rushes to return the campaign donations Of Norman Chu.
From a tactical point of view, it's smart. The story had run for several days; it reflected negatively on the campaign; so Clinton moved to cut any losses immediately and move on.
We're still left to wonder, though: did the Clinton campaign know the dirt about Hsu long ago, and take his money anyway? We don't know. We may never know. But if we some day find out they did, it won't be a good day for the Clinton campaign. Note also that she isn't returning all of the money; just $23,000 of it. Hmmm....
