Rev. Al Sharpton, a pal of both President Obama and Mayor de Blasio, "faces personal federal tax liens of more than $3 million, and state tax liens of $777,657," the New York Times reports. It adds that his non-profit, the National Action Network, has experienced a revenue boom recently in contributions "from large corporate sponsors." The Times doesn't name them or get into what they want or get for the sponsorship money, but it would be an interesting topic for additional journalism. It's something to consider in terms of President Obama and de Blasio, both of whom support higher taxes. When it comes to actually paying the taxes, it turns out to be, at least for people like Mr. Sharpton, essentially optional. The whole story is worth a look.
