Story highlights Rep. Chaffetz postponed his hearing with Comey earlier this week

Rep. Chaffetz announed last week he would leave Congress on June 30

Washington (CNN) House oversight committee Chairman Jason Chaffetz said Wednesday he had a "one-on-one" conversation with ousted FBI Director James Comey earlier this week, in which they discussed Comey's looming public testimony.

"Mr. Comey did not want to come testify publicly because of the presence of a special counsel," Chaffetz, a Utah Republican, told Wolf Blitzer on "The Situation Room."

The interview comes two days after Chaffetz announced he postponed his panel's hearing related to the FBI's independence scheduled for Wednesday.

"Spoke with Comey. He wants to speak with Special Counsel prior to public testimony. Hearing Wed postponed. @GOPoversight," Chaffetz tweeted.

The lawmaker, who announced last week that he will leave Congress on June 30 , said he and Rep. Elijah Cummings, a Maryland Democrat, both spoke with Comey. The former FBI director was fired by President Donald Trump amid the FBI's investigation into Russia meddling in the 2016 election.
