From an AP story by Eric Tucker headlined “Book sales, a lure for money and more takeaways from the AP investigation into Supreme Court ethics”:

In a monthslong inquiry, which included reviewing tens of thousands of pages of documents from more than 100 public records requests, The Associated Press has examined what happens behind the scenes when Supreme Court justices travel to colleges and universities for lectures and other events.

The AP learned the identities of donors and politicians invited to events with justices, details about the perks that have accompanied the school visits and information about how school trips have helped advance books sales.
