President Donald Trump has tweeted praise for nearly two dozen books shortly after watching their authors be interviewed on Fox, according to a Media Matters review of his Twitter feed and of Fox News and Fox Business programming during his presidency.

The president’s worldview and his policy and political decisions are shaped by the hours of Fox coverage he watches each day. He frequently tweets about segments that interest him in near-real time, triggering international incidents and congressional feuds.

But this Fox-Trump feedback loop also affects more mundane aspects of Trump’s behavior, including the tomes the president recommends. In fact, I first began tracking the president’s tweets against Fox’s programming after a colleague noticed that Trump had tweeted praise for a book minutes after its author appeared on Fox & Friends.

Trump is notoriously averse to reading anything but cable news chyrons. Asked about his book-reading habits in 2016, he said, “I read passages. I read -- I read areas, I read chapters. I just -- I don't have the time.” He then reeled off a list of Fox hosts whose programs he watches instead.

Those programs are frequently the source of Trump’s book recommendations, which are typically for hagiographies of Trump’s presidency, condemnations of his perceived enemies, or a combination of the two. Their authors are often Fox personalities (some of whom serve dual roles as outside presidential advisers) or former members of his campaign or administration.

Sometimes the hosts will simply mention their guests’ new book while introducing them at the top of an interview about the news of the day. Other times -- particularly on Fox & Friends, the president’s beloved morning show -- the authors appear specifically to discuss their books.

In their Fox interviews, these authors typically laud Trump and criticize his foes, catching the attention of the president, who surely knows little more about the book than what he’s seen on Fox. He then sends a tweet telling his followers to read their books, often just minutes after the segment airs. 

By my count, the president has praised 23 different books a total of 27 times after seeing the book promoted on Fox. 

Green Card Warrior: My Quest for Legal Immigration in an Illegals’ System by Nick Adams

Hannity referenced Pirro’s book while introducing her during the June 21, 2018, edition of his Fox show.
