Democratic senators pressed President Donald Trump’s pick for director of national intelligence on questions of election security and integrity Wednesday, but they didn’t leave his nomination hearing satisfied with the answers.

As is typical for Trump administration nominees, Jay Clayton wouldn’t answer definitively at his Senate Intelligence Committee confirmation hearing whether Joe Biden won the 2020 presidential election, saying only that he was “certified,” while maintaining that he wasn’t an “election denier.”

He said that the Office of the Director of National Intelligence’s responsibilities were “principally” outside the United States. But he claimed varying degrees of ignorance about his predecessor, Tulsi Gabbard, being physically present at an FBI raid of a Georgia election office in January, and wouldn’t comment on its appropriateness.

Democratic senators were also frustrated while trying to pin down Clayton, the U.S. attorney for the Southern District of New York who served as head of the Securities and Exchange Commission in Trump’s first term, on remarks about mail-in ballots and the California primary election results last month.

Multiple senators, including Mark Warner, D-Va., Angus King, I-Maine and Mark Kelly, D-Ariz., tried to get Clayton to say whether Biden won the 2020 election. The final exchange came with Jon Ossoff, D-Ga.

Clayton protested that he had already answered. “I think I’ve answered the question,” he said. “We can keep doing this.”

Ossoff didn’t agree, telling him, “Well we’re going to keep doing it because you’re not being honest or forthright with the committee.”

“Isn’t it humiliating to be unable to answer this question?” he asked. “To have to indulge the president’s delusions? We know, you know, everybody in this room knows the truthful answer to that question. Why can you not give it?”

Earlier Clayton had said, “I’m not an election denier,” but repeatedly wouldn’t answer “yes” or “no” on whether Biden won in 2020.

That matters because of the DNI’s role, Kelly said, and it was worrying that Clayton was seeking to avoid upsetting Trump, who has maintained despite all evidence that he lost the 2020 election.

“It’s not about softening the edges when the truth is unpleasant,” Kelly said. “It’s about delivering information.”

Clayton discussed the DNI’s role on election security at greater length in pre-hearing written answers.

“I understand that the DNI, as head of the Intelligence Community, has substantial statutory authority to address national intelligence threats to U.S. elections,” he said. “In particular, the Director is responsible for the integration of national intelligence, which may include foreign intelligence threats to U.S. election activity. I also understand that Intelligence Community elements are authorized to cooperate with and provide appropriate intelligence and technical support to law enforcement agencies and that as head of the Intelligence Community, the DNI has oversight of those activities.”

A CNBC interview last month inspired some of the Democrats’ questions. Clayton said in response to questions about the California primaries that “On the integrity side, we’re doing an absolutely terrible job. And the American people are right to question it.” 

He said mail-in ballots present an “opportunity for fraud,” despite studies showing exceptionally low rates of fraud using that method, and said “mail-in ballots being used by one group and not another… honestly and dishonestly” was a “question that everyone is now asking.”

Sen. Ron Wyden, D-Ore., asked him about what group Clayton was referring to.

“”I would like to see where you’re pulling those quotes from. I’ve been very careful about my remarks on this,” Clayton answered. “I’d like to see the whole passage.”

In his questionnaire, when asked if “it would be inappropriate for a DNI to comment publicly about unsubstantiated claims regarding mail-in-ballots and election fraud,” Clayton answered that “If confirmed as DNI, any representations I make to the public, including about elections, will be informed by timely, objective national intelligence.”

Ossoff also had a tense exchange with Clayton when asking him about Gabbard’s appearance at the Fulton County office raid. Gabbard has said she was there because Trump asked her to be, in what subsequently became a highly publicized appearance because of questions about what the DNI would be doing at a law enforcement raid.

“I was made aware of it by you yesterday,” Clayton said.

Ossoff responded skeptically: “The first time you learned that Director Gabbard was present at that raid was in my office yesterday?”

Said Clayton: “It was the first time that in my recollection I’ve thought about it recently.”

“What?” Ossoff replied.

Warner, the top Democrat on the committee, told Clayton “I trust you” but it “strains credulity” that he wasn’t aware of Gabbard being at the raid.

“To be clear, the ODNI’s role is principally outside of the United States,” Clayton said.

On other topics, in his opening remarks, Clayton touted his SEC work on cybersecurity. In his questionnaire he said he would work to facilitate cyberthreat information sharing from his office.

He told Sen. Kirsten Gillibrand, D-N.Y., that he would evaluate whether the DNI should devote more resources to cybersecurity with federal government cyber experts being pushed out since Trump came back to office. Many Republicans are pushing to further reduce the size of Clayton’s office, contending it has become bloated beyond Congress’ original intentions as a coordinating body.

He said he supported renewal of Section 702 of the Foreign Intelligence Surveillance Act, which gives the executive branch controversial spying powers that Congress recently allowed to expire.

Trump has threatened to block renewal unless lawmakers advance his priority election bill. He said he will study how to “minimize the detrimental impact to our national security caused by the lapse in 702 authorities.” Some Democrats, meanwhile, have resisted action on the law until Trump’s pick for acting DNI Bill Pulte is gone, citing his prior efforts to investigate officials as head of the Federal Housing Finance Agency and lack of intelligence experience.

Because the GOP controls the Senate, Clayton is likely to get confirmed as DNI as long as no Republicans emerge in opposition. Wednesday’s hearing revealed no significant Republican objections.

Intelligence Chairman Tom Cotton, R-Ark., touted Clayton’s experience prosecuting terrorism cases and more.

“Jay Clayton has worked hand in glove with our intelligence agencies and counterterrorism personnel to lock up criminals who threaten our national security,” Clayton said. “I encourage my colleagues to join me and get Mr. Clayton’s nomination over the finish line.”
