Former CIA Director John Brennan said Thursday he would gladly testify to Congress.
"I am happy to talk to them just the way I spoke to John Durham, the Department of Justice, or any other committee on the hill," he added later.
Durham is the U.S. Attorney leading the criminal investigation into Crossfire Hurricane, the FBI's previous counter-intelligence probe into Donald Trump's campaign.
Brennan had begun saying that Chairman Lindsey Graham (R-S.C.) and Senate Homeland Security Chairman Ron Johnson (R-Wis.) "don’t have the—" and appeared to mouth or say an expletive before starting over. "They don't have the interest in calling me up in front of their committees and to testify publicly in front of the American people," he said.
The investigations into Crossfire Hurricane are "a hyper-partisan, politically corrupt effort to try to create an environment prior to the election that cast Donald Trump in a positive light and Joe Biden in a negative light," he added.
Graham said publicly in May that he would call Brennan but has not done so.
The dossier compiled by ex-British spy Christopher Steele and paid for by Hilary Clinton's campaign and the Democratic National Committee "is a bunch of political garbage, unverified to this day," Graham said at the time. "Why was it included in the intel assessment? Did Brennan have anything to do with that?"
Johnson has said he was waiting on various documents to subpoena certain figures. He has only subpoenaed one person, former State Department official Jonathan Winer, so far, along with records from the FBI.
Neither Brennan nor Johnson responded to inquiries on Friday.
In the new interview, Brennan said he believes Durham's team was "testing various theories that they had heard and were asking for my views as well as my recollections on things."
"But it was handled in a very professional manner," he added.
Brennan then expressed concern about the resignation of Nora Dannehy, who was working for Durham.
Barr has said he feels no pressure to produce results before the election and that Durham's team is not working on a specific timeline.
