FBI Director James Comey and NSA chief Mike Rogers are not expected to appear Tuesday at a closed hearing of the House Intelligence Committee, Fox News confirmed.

Tuesday's appearance would have followed up on the pair's open testimony last week on the topic of Russian meddling in the presidential election and the alleged mishandling of intelligence related to the Trump transition team.

"Director Comey and Adm. Rogers could not come in tomorrow as we’d hoped, so the Committee will continue to try to schedule a time when both of them can meet with us in closed session," a spokesperson for Chairman Devin Nunes, R-Calif., said in an email to Fox News.

Former Director of National Intelligence James Clapper and ex-CIA Director John Brennan were originally scheduled to appear during an open hearing Monday. However, Nunes canceled those appearances because he wanted to hear in private from Comey and Rogers after Nunes revealed last week he had seen incidental intercepts of Trump team communications. Nunes said he had seen other members of Trump's team "unmasked" and their identities widely disseminated throughout the government. Other members of the Intelligence Committee had yet to see the documents shown to Nunes.

Comey and Rogers still could come at a later date.

There will now be no hearing on Tuesday, though Nunes' office noted that didn't mean the hearing was canceled -- because it had never officially been scheduled.

"We tried to get it organized for tomorrow, but it didn’t work out," a spokesperson said.
