Rep. Paul Ryan (R-Wis.) has selected David Hoppe, a former adviser to Republican congressional leaders and a longtime Washington lobbyist, to serve as his chief of staff, should Ryan be elected House speaker this week, as is widely expected. The hiring was finalized after Hoppe and Ryan, both Wisconsin natives and proteges of the late New York congressman Jack Kemp, had conversations about Ryan’s desire to staff the speaker’s office with seasoned aides who are also deeply familiar with conservatism, according to people briefed on the talks.
