(WASHINGTON) — Illinois Rep. Aaron Schock, a rising Republican star already facing an ethics inquiry, has spent taxpayer and campaign funds on flights aboard private planes owned by some of his key donors, The Associated Press has found. There also have been other expensive travel and entertainment charges, including for a massage company and music concerts. The expenses highlight the relationships that lawmakers sometimes have with donors who fund their political ambitions, an unwelcome message for a congressman billed as a fresh face of the GOP.
