If you’re an ambitious member of Congress with a national profile, there’s a tried and true way to make some extra money: write a book.
According to recently filed financial disclosures, 8 sitting US senators made more than $100,000 in extra income — on top of the $174,000 annual salary they each receive — from book royalties in 2023.
