“I’m sure there will be plenty of ingenious individuals thinking about what to do on those committees,” said Sen. Mike Braun (R-Ind.).

Braun, while noting he didn’t have a pet investigation, pointed to GOP Sens. Rand Paul (R-Ky.) and Ron Johnson (R-Wis.) as two examples of GOP senators who could have “some real interest in looking into stuff that has not been attended to.”

Johnson, if he wins his reelection bid in November, is poised to chair the Homeland Security and Governmental Affairs Committee’s permanent subcommittee on investigations. Johnson is prevented because of term limits from chairing the full committee again, but the subcommittee gavel comes with a crucial element: subpoena authority.

Asked if there were overlooked issues that he would want to probe, Johnson appeared eager to dig in.

“Like everything?” he told The Hill. “It’s like a mosquito in a nudist colony, it’s a target rich environment.”
