Conspiracies surrounding Russian meddling in American politics used to be the terrain of novelists. Now nonfiction writers get to dig in. Hillary Clinton’s “What Happened,” her account of the 2016 presidential election, went on sale Tuesday, and another book about the election, an investigative look by two journalists into the controversies surrounding Donald J. Trump, Vladimir Putin and Russia’s influence, isn’t far behind.

Twelve, an imprint of Grand Central Publishing, will release the book by Michael Isikoff and David Corn in March. According to the publisher, the book, tentatively titled “The Russian Connection,” will go behind the scenes of Russia’s attempts to influence the election, and will also analyze Trump’s decades-long dealings with Russia as well as the historical relationship between the two countries.

Corn and Isikoff previously teamed up to write the 2006 best seller “Hubris: The Inside Story of Spin, Scandal, and the Selling of the Iraq War.” Isikoff is the chief investigative correspondent for Yahoo News. Corn is the Washington bureau chief for Mother Jones magazine and an analyst for MSNBC.
