[A timeline of the case|What we know about the evidence]

Mr. Smollett, 37, was charged last February with filing a false police report after the Chicago police concluded that he had paid two brothers to stage an attack on him in which they shouted homophobic and racial slurs and yelled, “This is MAGA country,” a reference to President Trump’s 2016 campaign slogan. The police said Mr. Smollett was looking for publicity because he was unhappy with his salary on the television show “Empire,” which dropped him from the cast after his arrest.

The new indictment charges Mr. Smollett with six counts of disorderly conduct related to false statements to Chicago police officers. Five of the counts were related to accounts Mr. Smollett gave police the morning of Jan. 29, 2019, when he said the attack occurred; and one was related to a statement he made on Feb. 14, around when the police started to view Mr. Smollett as a suspect.

In a statement, Tina Glandian, a lawyer for Mr. Smollett, noted that he is in litigation with the Chicago Police Department, and raised questions about whether it was fair for Mr. Webb to partly base his investigation on evidence from that department. She highlighted the fact that Mr. Webb’s office said it had not yet found evidence of wrongdoing on the part of the prosecutors.

“The attempt to re-prosecute Mr. Smollett one year later on the eve of the Cook County State’s Attorney election is clearly all about politics not justice,” she said in the statement.

Ms. Foxx is running for re-election and faces a Democratic primary next month in which her opponents have criticized her management of the Smollett case. Her campaign issued a statement on Tuesday denouncing the “James Comey-like timing” of the new charges, referring to the former F.B.I. director’s public pronouncements about the investigation into Hillary Clinton’s email server just before she lost to Mr. Trump.
