The state’s political corruption probe is back in the news.

A state grand jury indicted longtime Republican political power broker Richard Quinn Sr. with new criminal corruption charges last week.

Another defendant, former House Judiciary Committee Chairman Jim Harrison, was sentenced to 18 months in prison for lying to a grand jury and misconduct in office.

But circuit court judge Carmen Mullen granted Harrison a $250,000 bond that allows him to remain free while he appeals his conviction.

Special prosecutors so far have won convictions but been unable to send anyone to prison.

A new 38-page indictment charges Quinn with 12 counts of perjury and two counts of obstruction of justice.

Quinn’s son Rick Jr. represented Lexington County in the House until he pleaded guilty to corruption and was removed from office.

Another Quinn client, Sen. John Courson who represented Lexington County, also admitted corruption and lost his office.

The new indictment is similar to one in April 2019 when the state grand jury was led by former Statehouse corruption prosecutor David Pascoe.

The newest grand jury finding, led by special prosecutor Barry Barnette was made May 20 but not made public.

The Charleston Post and Courier obtained a copy July 2.

A grand jury 1st indicted Quinn in 2017 for criminal conspiracy and failure to register as a lobbyist.

His son pleaded guilty in a deal requiring Quinn to testify before the grand jury.

The indictment alleges that Quinn:

• Told the grand jury he paid Harrison to help run political campaigns. Yet witnesses testified Harrison did little or no campaign work for Quinn but was paid $900,000 over 12 years to propose and vote for bills to benefit Quinn’s clients.

Quinn, sr. denied a kickback scheme with former Sen. John Courson who admitted taking $133,000 in campaign money.

He also denied paying his son who voted as a lawmaker on bills benefiting his clients.
