So, you missed the part about nepotism? From your link.
Such payments are not illegal, but some watchdog groups say they raise questions about nepotism. "It's a form of self-dealing and anytime you're involved with self-dealing, questions are going to be raised," said Larry Noble, head of the Center for Responsive Politics, a Washington-based campaign finance watchdog group.
When the Bennington Banner and Brattleboro Reformer carried a story about the payments on Wednesday, Vermont Republican Party Chairman James Barnett said he smelled hypocrisy.
"I think Bernie Sanders needs to be held to the same standard that the left is holding Congressman DeLay to," he said. "If it's wrong when Congressman DeLay does it then it's wrong when Congressman Sanders does it."
No, you did not miss that. You would prefer to pretend it wasn't there.
