Alabama House Speaker Mike Hubbard, the architect of the state Republican Party’s remarkable turnaround, was indicted Monday on 23 counts of using his office for personal gain and soliciting things of value while in office.

If convicted, the 52-year-old Hubbard could face up to 20 years in prison and $30,000 in fines for each count.

Hubbard on Monday turned himself in to the Lee County Jail, where he was photographed and booked. In a video posted to Facebook, Hubbard called the charges “a political witch hunt.”

“This has been going on for two years, dragging on and on, and here they come two weeks before an election and make these allegations. The fact is that we’ve done some great things in this state and some powerful people don’t like it,” Hubbard said in the video. “This is politics at its worst.”

Hubbard’s lawyer said he will hold a press conference Tuesday to rebut the charges.

A Lee County grand jury charged Hubbard with four counts of using his office as chairman of the state Republican Party for personal gain, and two counts of using his public office for personal gain. The charges also include 11 counts of soliciting or receiving a thing of value from a lobbyist, four counts of lobbying an executive department for a fee and one count of using state equipment for personal gain, the Montgomery Advertiser reported.

The indictment alleges Hubbard sought favors from some of the state’s best-connected political figures, including former Gov. Bob Riley (R) and the CEOs of major business and construction firms.

The grand jury was convened last year in Lee County to look into the case. Attorney General Luther Strange (R) recused himself from the investigation and handed it over to a former county district attorney. Already, two other legislators have been charged in the investigation.

In April, state Rep. Greg Wren (R) pleaded guilty to a charge of using his office for personal gain, resigned his seat and agreed to cooperate with investigators. State Rep. Barry Moore (R) was charged with perjury, to which he has pleaded not guilty. Moore’s trial is scheduled to begin Oct. 27.

Hubbard has been a major figure in the Alabama Republican Party’s resurgence over the last decade, after more than a century of Democratic dominance. He was the first Republican to be elected speaker of the state House since Reconstruction, after leading the GOP to a majority in 2010.
