The Amateur author Edward Klein has signed a two-book deal with HarperCollins’ William Morrow imprint.

According to CBS News, one of the books will profile the 2016 presidential nominee of the Democratic party. The other will spotlight on politicians who promote “the left-wing political agenda.”

In the past, Klein has written books about the President John F. Kennedy, former First Lady Jacqueline Kennedy Onassis, secretary of state Hillary Clinton and President Barack Obama. Prior to establishing his publishing career, Klein worked in journalism. He served as an editor at both Newsweek and The New York Times Magazine.
