On Sunday, he will speak at a meeting of the local chapter of the National Association for the Advancement of Colored People in his hometown of Manning.
"I told them I would talk about jobs, education and justice," which he says are the core issues of his campaign, Greene told CNN Monday.
Greene's victory in the June 8 primary shocked many political observers since Greene had not actively campaigned for the nomination and he had no political experience.
His financial situation also caused him to come under scrutiny when he was faced with questions about how as an unemployed veteran he could afford the $10,440 filing fee required to enter the campaign. He has said it came from savings he accumulated while serving in the military.
Last year, he also said he could not afford a lawyer to defend himself on charges of showing pornographic messages to a college student. He has not entered a plea in that case and has previously told CNN he is innocent until proven guilty.
After an investigation, the South Carolina South Carolina Law Enforcement Division on Friday cleared Greene of any wrongdoing concerning that issue.
"SLED has concluded that there is no evidence of wrongdoing, criminal intent or deception to the court when Greene applied for a public defender last year," the agency said in a statement Friday.
"During the course of the investigation, SLED determined that monies spent for Greene's filing fee were the candidate's personal funds and therefore, no laws were violated in association with Greene's payment to the South Carolina Democratic Party," SLED said.
Greene is thought to stand little chance in November against Sen. Jim DeMint, the incumbent Republican who has $3.5 million in his campaign account.
