Brennan voiced his eagerness to challenge Trump on the same day that national security adviser John Bolton floated the idea of a sweeping review of all security clearances held by those both inside and outside the government. Such a review could affect more than 4 million Americans.
Brennan, who is among Trump’s most outspoken critics, was abruptly stripped of his clearance by the White House last week. Brennan said Sunday that since then, a number of lawyers have contacted him to offer advice on pursuing an injunction to prevent Trump from taking similar actions in the future.
“If my clearances — and my reputation, as I’m being pulled through the mud now — if that’s the price we’re going to pay to prevent Donald Trump from doing this against other people, to me, it’s a small price to pay,” Brennan said.
He did not elaborate on what such a legal move would entail.
Asked during an appearance on Fox News Channel’s “Sunday Morning Futures” about a possible lawsuit by Brennan, Rudolph W. Giuliani, Trump’s personal attorney, described it as a welcome opportunity.
“I would volunteer to do that case for the president. I would love to have Brennan under oath,” Giuliani said. “We will find out about Brennan, and we will find out what a terrible job he did.”
On Friday, more than a dozen former top CIA officials and a former director of national intelligence penned a statement denouncing Trump’s action against Brennan as “an attempt to stifle free speech.”
Trump told the Wall Street Journal last week that he revoked the clearance because of Brennan’s role in the “sham” Russia probe being led by special counsel Robert S. Mueller III. That explanation appeared to contradict Trump’s earlier official statement, in which he said he took the move because Brennan “has a history that calls into question his objectivity and credibility.”
As furor over Trump’s actions has intensified, the president has shown no signs of backing down. According to senior administration officials, the White House is preparing paperwork to strip the clearances of several other current and former officials who have either sharply critiqued Trump or have played a role in the Russia probe.
The Trump administration’s scrutiny of security clearances could extend well beyond that list, Bolton suggested.
In an interview on ABC News’s “This Week,” Bolton cited an era of “unprecedented” classified leaks as justification for a formal review of individuals holding security clearances.
“I think it’s certainly appropriate, in a time when we’re seeing what I believe are unprecedented leaks of highly classified information, to look at the question of how many people have clearances, how many people received this very sensitive information, both inside the government and in the case of former officials,” he said.
Nearly 4.1 million Americans hold federal security clearances up to the “top secret” level, according to government estimates. Former officials commonly retain their clearances, some to provide advice to current administration officials and others because they hold jobs requiring clearances.
Bolton said that he did not consider a political disagreement sufficient grounds for an official to have a security clearance pulled but that violating the separation between intelligence and policy would be grounds.
He said that “senior intelligence officials, career intelligence officials who come out of the government,” should “keep that wall of separation” between intelligence and policy, and that Brennan had not done so. Bolton later added, “There is a line, and somebody can cross it.”
Trump’s stripping of Brennan’s clearance has stirred debate over whether the president followed proper procedures in making the move.
Mark Zaid, an attorney who specializes in national security law, said that under an executive order on access to classified information, Brennan may be entitled to legal representation and a written explanation of the reasons for the loss of his clearance.
“But the question is whether any agency official could realistically or legally overturn the president’s decision,” Zaid said. “So, it could be a right without a remedy.”
Civil litigation might also be possible, he said, although federal courts have been hesitant to wade into clearance disputes.
Former CIA director Leon Panetta also cast doubt on whether Trump acted in accordance with the executive order.
“I think there are questions raised as to whether or not this president has followed the executive order and whether or not he’s provided due process to those that are going to have their security clearances revoked,” Panetta said. “Yes, the president of the United States has power, but that power is limited by the Constitution and by the checks and balances in our system.”
Brennan on Sunday described himself as having “a bull’s eye on my chest,” even as he continued to defend some of his most inflammatory remarks.
In the “Meet the Press” interview, he defended his previous statement denouncing Trump’s performance last month at a summit with Russian President Vladimir Putin in Helsinki as “treasonous.” Some of Brennan’s detractors have argued that the remark pushed his criticism of Trump into overly partisan territory.
“I called his behavior ‘treasonous,’ which is to betray one’s trust and to aid and abet the enemy,” Brennan said. “I stand very much by that claim.”
In an interview on “Fox News Sunday,” Sen. Ron Johnson (R-Wis.) said the former CIA director had “abused his privilege” by using that word to describe Trump’s behavior.
“He’s one of the leaders of the resistance movement. I understand why President Trump is pretty frustrated,” Johnson said.
Bolton also argued that Brennan would not have been able to criticize Trump’s “so-called collusion with Russia unless he did use classified information,” although he said he has no knowledge of a single specific instance.
“What I do know was when he was director of CIA, I was very troubled by his conduct, by statements he made in public and by what I thought was his politicization of the intelligence community,” Bolton added.
Others rallied to Brennan’s defense Sunday.
Mike Mullen, a retired Navy admiral and former chairman of the Joint Chiefs of Staff, said Trump’s threat to revoke the security clearances of his critics is a sign that the president is “creating a list of political enemies.”
“It immediately brings back the whole concept of the ‘enemies list’ under President Nixon,” Mullen said in an appearance on “Fox News Sunday,” adding that it was also reminiscent of the anti-communist crusade led by Sen. Joseph McCarthy in the 1950s.
Former CIA director Michael V. Hayden, whose security clearance the White House has warned is also in danger of revocation, said during an appearance on CNN’s “State of the Union” that the relationship between the president and the national security community is “dangerously close to being permanently broken.”
“Frankly, although John’s situation is the proximate cause for all of us signing letters and protesting, I think it’s kind of one additional straw that’s breaking the camel’s back,” Hayden said. “Our complaint is not just about this. It’s about the whole tone, tenor and behavior of the administration.”
Former director of national intelligence James R. Clapper Jr. sounded a similar note, saying on CNN that while Brennan’s rhetoric has become “an issue in and of itself,” his remarks are indicative of the “genuine concern about the jeopardy or threats to our institutions and values.”
