Simon & Schuster

The provided articles do not mention Simon & Schuster. Therefore, a summary about the organization based on these articles is impossible. The first article details Tucker Carlson's launch of a publishing imprint, 'Tucker Carlson Books,' under Skyhorse Publishing, featuring authors like Russell Brand and Milo Yiannopoulos. The second article references Jill Biden's memoir, which discusses Joe Biden's decision to end his 2024 reelection bid. Without information about Simon & Schuster's involvement in either of these events, or any other context provided in the articles, I cannot provide a relevant summary about them.
