In 'Crime In Progress,' Fusion GPS Chiefs Tell The Inside Story Of The Steele Dossier

There's an unverified story that has circulated placing Donald Trump in the presidential suite of the Moscow Ritz-Carlton in 2013.

NPR has not detailed it because it remains unverified. Trump and his supporters have called it outrageous and ridiculous.

So where'd it come from?

Seven Russian sources told British specialist Christopher Steele the hotel anecdote, write Glenn Simpson and Peter Fritsch in their new book Crime in Progress: Inside the Steele Dossier and the Fusion GPS Investigation of Donald Trump.

Simpson and Fritsch, former Wall Street Journal reporters, are the founders of the now-famous or notorious private intelligence firm Fusion GPS. They hired Steele to investigate Trump and said they too were surprised about what came back.
