(CNN) - New Jersey Gov. Chris Christie gave a firm "no" Monday when asked if he's been subpoenaed personally as part of a federal investigation of the George Washington Bridge scandal.
Christie made the comments on New Jersey 101.5's monthly "Ask the Governor" radio program.
"We are fully cooperating with the U.S. attorney's office," Christie said.
He was responding to a question about the ongoing investigation of suggestions top appointees in his administration orchestrated traffic ties ups in Fort Lee near the nation’s busiest bridge last year in an act of political retribution.
Separate from the probe by federal prosecutors, a special state legislative committee is considering issuing more subpoenas and begin hearing testimony soon as part of its investigation of the matter.
The Democratic co-chair of the panel, Assemblyman John Wisniewksi, has not ruled out calling Christie to testify.
Asked if he would consider doing so, Christie quickly responded: "I'm not going to talk about it."
An internal review by outside lawyers hired by Christie's office cleared him of any wrongdoing. But critics say the investigation was incomplete.
