Longtime sportswriter Rick Reilly has a new book set for release unlike anything he's written before.

Commander in Cheat: How Golf Explains Trump will be released in May, Hachette Books announced on Wednesday. The book is based off interviews with and observations from former playing partners and caddies of President Trump over the years.

Reilly gained national acclaim for his back page columns in Sports Illustrated in the early 2000's before moving to ESPN in 2008 to be a featured columnist and show host.

Reilly has written numerous books, including a handful about golf, such as 2003's Who's Your Caddy, where he details a round in which he caddied for Trump.

Commander in Cheat isn't the only book about Trump making headlines this week. Fear: Trump in the White House, by Watergate reporter Bob Woodward, has caused a stir after the Washington Post published excerpts of the book, which details chaos in the White House during the Trump administration.
