As the pages on the calendar fly by, U.S. Rep. Darin LaHood's rhetoric is heating up about the lack of a top prosecutor for central Illinois.

He was one of the GOP lawmakers who helped serve as gatekeeper in the process in spring 2017, selecting from a batch of several dozen applicants a set of four nominees.

Those four were also signed off on by the state's two Democratic senators and the list has been at the White House since last summer while folks in the office have held the job on an interim basis.

When we spoke to LaHood about it in March, he said he was frustrated by the delay and hoped it could be resolved within the next three months.

Well, that time has passed with no action. And earlier this month LaHood told us the administration is now aiming for the end of the summer.

"I think that's been too long," he told us. "I think it's ridiculous that we're 18 months into this administration and we don't have a U.S. attorney for this district."

LaHood praised the smart, bright reputation of the employees in the office for the U.S. Attorney for the Central District of Illinois and said it's a little bit of an embarrassment that there's not someone designated by the administration at their head.

Of course that person, when named, has some big cases ahead including the prosecution of U.S. Rep. Aaron Schock in a trial tentatively set for February 2019 (after a host of delays of its own). They'd also, it seems, be the ones watching the inquiry into Caterpillar, Inc. that featured in last year's multi-building raid of the Fortune 100 company for documents.

Through month's end when the congressional August recess begins, LaHood said he plans to pressure the White House to get someone named by the end of August.
