Mayor Vincent C. Gray is not joining some D.C. Council members’ calls for council member Harry Thomas Jr. to resign.

He said in a brief interview Tuesday that he would continue to “let justice run its course.”

On Friday, Thomas (D-Ward 5) settled a lawsuit with the city by agreeing to repay $300,000 that Attorney General Irvin Nathan says he diverted from youth programs for his own gain. The settlement does not prevent potential criminal charges.

Thomas has denied wrongdoing.

Council members David A. Catania (I-At Large), Mary M. Cheh (D-Ward 3) and Tommy Wells (D-Ward 6) have called for Thomas’s resignation as government watchdogs have equated the settlement with an admission of guilt.

Gray (D), a political ally, said he would not join the chorus, but he noted that he told Nathan to go forward with the investigation of Thomas that began under the administration of then-Mayor Adrian M. Fenty.

“I was the one who told Irv to move full speed ahead with the investigation,” Gray said.

Nathan has referred the matter to the U.S. attorney’s office.
