Co-founders Glenn Simpson and Peter Fritsch's book, which is due out Nov. 26, is being called an " 'All the President's Men' for the Trump era" by publisher Penguin Random House.

"After four years on his trail, the authors' inescapable conclusion is that Trump is an asset of the Russian government, whether he knows it or not," the publishing house says.

The political research firm commissioned former British spy Christopher Steele to investigate then-presidential candidate Trump's ties to Moscow and concluded the Russian government had information on the now-president.

Trump has repeatedly attack the dossier as "fake," but multiple allegations contained in it have been confirmed by subsequent reporting.
