Horowitz's "Big Agenda" — the first major book on the Trump administration — debuted at No. 6 for hardcover nonfiction books on the Times best-seller list before climbing to No. 5 and remaining there for many weeks.
The book, released the week of Trump's inauguration in January, has also hit the No. 1 bestseller in several Amazon categories.
"I hope that everybody listening to this show and that all the grass-roots Republicans out there, conservatives, will pick up the phones to their congressional offices and stick it to these guys," Horowitz told host Joe Pagliarulo.
