The review of Crowley’s June 2012 book, "What The (Bleep) Just Happened," found upwards of 50 examples of plagiarism from numerous sources, including the copying with minor changes of news articles, other columnists, think tanks, and Wikipedia. The New York Times bestseller, published by the HarperCollins imprint Broadside Books, contains no notes or bibliography.

In the book, Crowley lifted an entire section on Keynesian economics from the IAC-owned website Investopedia.

In one instance, Crowley lists a variety of so-called "pork" items she claimed were part of the 2009 stimulus package. Many of the instances were copied wholesale from a conservative list of pork barrel spending, with some items dating back to the 1990s. Most of the copied instances were listed on a website for a podiatrist dating back to 2004.

A section on organized labor appears largely copied from a 2004 article by the libertarian think tank the Mises Institute. Another portion of her book on torture is copied from a Fox News article.

Crowley has been accused of plagiarism before. In 1999, Slate reported a column by Crowley in the Wall Street Journal mirrored a 1988 article in Commentary, the neoconservative magazine.

Monica Crowley, President-Elect Donald J. Trump’s pick for a top National Security Council job, plagiarized numerous passages in her Ph.D. dissertation, Politico Magazine has found.

An examination of the dissertation and the sources it cites identified more than a dozen sections of text that have been lifted, with little to no changes, from other scholarly works without proper attribution. In some instances, Crowley footnoted her source but did not identify with quotation marks the text she was copying directly. In other instances, she copied text or heavily paraphrased with no attribution at all.

This finding comes on the heels of CNN’s Saturday report that Crowley, the conservative author and commentator whom Trump tapped as senior director of strategic communications for the National Security Council, plagiarized more than 50 passages in her 2012 book What the (Bleep) Just Happened, copying directly from conservative columns, news articles, Wikipedia and in one case a podiatrist’s website.
