From Peggy Noonan writing at the Wall Street Journal:
Check this out:

I have read the Peter Schweizer book “Clinton Cash: The Untold Story of How and Why Foreign Governments and Businesses Helped Make Bill and Hillary Rich.” It is something. Because it is heavily researched and reported and soberly analyzed, it is a highly effective takedown. Because its tone is modest—Mr. Schweitzer doesn’t pretend to more than he has, or take wild interpretive leaps—it is believable.

By the end I was certain of two things. A formal investigation, from Congress or the Justice Department, is needed to determine if Hillary Clinton’s State Department functioned, at least to some degree and in some cases, as pay-for-play operation and whether the Clinton Foundation has functioned, at least in part, as a kind of high-class philanthropic slush fund.
