EXCLUSIVE — Iowa state Sen. Zach Wahls has built his U.S. Senate campaign around a message of standing up for working-class voters, but his time in public offices shows a taste for luxurious hotels, flights to coastal enclaves, and high-end eateries.

Internal Iowa Democratic Party records from Wahls’s time as the Democratic leader in the state Senate show thousands of dollars in reimbursements for travel, lodging, and meals, including a string of high-cost flights and hotel stays that far exceed what other party leaders have reported.
