The easiest way to research national charities is with the three major charity watchdogs: Charity Navigator, CharityWatch, and the BBB Wise Giving Alliance. They rate charities based on how they spend their money, protect donor privacy, govern themselves, and more. Some have tools to sort and search for organizations and reviews. They use somewhat different criteria and don't always agree, so check out a charity with all three groups. [consumer reports]

That's what I found so far. The New York Post is a terrible source of information. They sensationalize titles just to sell papers or advertisement. The Clinton's name will be cleared again and people will cry "foul". At least I post all the information.
