If she is confirmed as director of national intelligence, Tulsi Gabbard would be the youngest-ever in that role, the first millennial, the first Asian American, and only the second woman to hold the position.

But she is expected to face questions in her confirmation hearing before the Senate Intelligence Committee about statements she has made that appear to support U.S. enemies and dictators as well as having no significant experience in intelligence. Gabbard can afford to lose the votes of only three Republicans and sources tell ABC News the vote on her nomination is expected to be a close one.

Chairman Tom Cotton, R-Ark., began his opening statement by expressing “dismay” at what he characterized as unfair attacks on Gabbard’s patriotism, citing Hillary Clinton’s accusation that she was “an asset of a foreign nation,” referring, of course, to Russia.

Cotton said he personally “spent two hours” reviewing Gabbard’s past background checks and found them “clean as a whistle.”

“No doubt she has some unconventional views,” Cotton acknowledged, but suggested any criticism from Democrats reflects their frustration that she “saw the light” and left their party.

In his opening statement, Sen. Mark Warner, D-Va., the committee’s top Democrat, ticked through a litany of Gabbard’s more controversial public statements to demonstrate what he called his “significant concerns about your judgment and your qualifications.”

“Now I don’t know if your intent in making those statements was to defend those dictators, or if you were simply unaware of the intelligence and how your statements would be perceived,” Warner said. “In either case, it raises serious questions about your judgment.”

In her opening statement, Gabbard confronted her critics.

“I want to warn the American people who are watching at home. You may hear lies and smears in this hearing that will challenge my loyalty to and my love for our country,” she said. “Those who oppose my nomination imply that I am loyal to something or someone other than God, my own conscience and the Constitution of the United States, accusing me of being Trump’s puppet, Putin’s puppet, Assad’s puppet, a guru’s puppet, Modi’s puppet, not recognizing the absurdity of simultaneously being the puppet of five different puppet masters.

“The same tactic was used against President Trump and failed. The American people elected President Trump with a decisive victory and mandate for change. The fact is, what truly unsettles my political opponents is I refuse to be their puppet,” she continued.

For most of her career, Gabbard has broken barriers. She was the youngest woman ever elected to a state house of representatives and the first to graduate from the Accelerated Officer Candidate School at the Alabama Military Academy as a distinguished honor graduate. In Congress, she was the first Samoan American, the youngest woman elected at the time, and the first combat veteran to serve — a distinction she shares with Illinois Sen. Tammy Duckworth.

Gabbard has prepared extensively over the past two months for her hearings, meeting with former DNI leaders, including John Negroponte, the first DNI, and Michael Allen, who led Negroponte’s confirmation hearing preparations. She also has consulted with Trump allies Morgan Ortagus, deputy special presidential envoy for Middle East peace, and FBI director nominee Kash Patel.

She has sought input from a broad range of intelligence experts, former government officials and lawmakers across the aisle. She has participated in policy roundtables with lawyers, ex-intelligence officials, and national security negotiators, including figures involved in the Abraham Accords.

She also held a full-scale mock confirmation hearing ahead of Thursday’s Senate Intelligence Committee proceedings. Former Republican Sen. Richard Burr, who chaired the committee from 2015 to 2020, will introduce her.

Sources on both sides of the aisle on Capitol Hill tell ABC News Gabbard will likely face scrutiny over her past stances on Russia, Ukraine, Syria, and Iran, as well as her defense of WikiLeaks founder Julian Assange, who reached a plea deal with the Justice Department over disseminating classified documents he had obtained illegally. Gabbard said last year on “Real Time With Bill Maher” that “the charges against him are one of the biggest attacks on freedom of the press that we’ve seen and freedom of speech.”

As a member of Congress, Gabbard introduced a bill in 2020 calling for the federal government to drop all charges against Edward Snowden, the former NSA contractor who leaked information in 2013 about how the U.S. government surveils the American public.

She’s also expected to face question on her reversal on Section 702 of the Foreign Intelligence Surveillance Act (FISA), a key surveillance tool she voted against reauthorizing in 2020, her last year in Congress.

Gabbard argued that Americans shouldn’t be forced to choose between security and liberty, saying that the Patriot Act and FISA have “been allowing for the abuses of our civil liberties and overreach by our own intelligence and law enforcement agencies through doing things like warrantless sweeping collection of our data, violating our Fourth Amendment constitutional rights.”

Gabbard is also expected to face questions past statements about former President Donald Trump including her decision to vote present on Donald Trump’s.

Over the last two months, Gabbard has met with more than 50 senators, primarily Republicans. The meetings have largely served as an introduction — an opportunity to explain her past positions and assuage concerns about her political evolution. A source close to her told ABC News, “They know they can’t put her in a box. She’s not a Democrat. She’s a new Republican. She has very similar, if not 100% aligned, views with President Trump on ‘America First’ foreign policy. That makes people uneasy because they can’t quite figure her out.”

Gabbard, like Trump, is a former Democrat whose policy views have shifted significantly. Her evolution has been shaped by her 22 years in the Army, including deployments to Iraq, Kuwait, and Djibouti. If confirmed, she will be the first female DNI to have served in the military. She plans to continue serving in the Army Reserve, which is permitted under ODNI regulations.

Behind the scenes, Gabbard has earned bipartisan support within the intelligence community for her willingness to engage with a range of stakeholders. Earlier this month, the families of two former ISIS and al-Qaeda hostages publicly endorsed her nomination in a letter shared with ABC News. The parents of Kayla Mueller, who was killed by ISIS, and Theo Padnos, a former al-Qaeda hostage, argued that the radicalization of individuals — such as Shamsud-Din Jabbar, who drove his truck into a crowd of New Orleans New Year’s revelers — underscores the need for Gabbard’s swift confirmation.

The letter of support came under scrutiny by some lawmakers after rebels toppled Syria’s Bashar al-Assad. Gabbard met with Assad in Syria in 2017, which remains a point of controversy. She has previously defended the trip as a “fact-finding mission” and has maintained that U.S. intervention in Syria empowered extremist groups.

Gabbard warned in the same year that she was concerned that toppling Assad’s regime could lead to groups like ISIS and al-Qaeda to step in to fill the void and “completely massacre all religious minorities there in Syria.”

“I had no intention of meeting with Assad, but when given the opportunity, I felt it was important to take it,” Gabbard said in a 2017 statement. “We should be ready to meet with anyone if there’s a chance it can help bring about an end to this war.”

Padnos, who was kidnapped by the al-Nusra Front in 2012 and held for nearly two years, said Gabbard’s willingness to engage with hostage families compelled him to speak out.

“This is a woman with deep compassion for the victims of terrorism and the courage to get things done,” he told ABC News. “Nobody else has offered their help — except Tulsi.”

Gabbard told ABC News that she was “honored and humbled by that statement of support.”

She has also received backing from law enforcement. The National Sheriffs’ Association endorsed her nomination, citing her commitment to bridging intelligence gaps between federal agencies and local authorities. In a statement, the group praised Gabbard’s pledge to give sheriffs “a seat at the table” in national security discussions.

Sheriff Kieran Donahue, president of the National Sheriffs’ Association, wrote “Gabbard has demonstrated a commitment to addressing the critical disconnect between our intelligence agencies and local law enforcement in preparing for sophisticated and pervasive threats.”

A source close to Gabbard told ABC News that her focus as director of national intelligence will be on restoring trust in the intelligence community and reforming what is and isn’t classified. Specifically, she aims to ensure that the intelligence provided to the Senate and White House is not information already available to lawmakers through media outlets. On Capitol Hill, lawmakers have expressed concern about the overclassification of information.

The source added that Gabbard intends to provide more accurate, raw intelligence to help lawmakers make informed decisions, rather than relying on overclassified data. She also plans to streamline the process for security clearances and return ODNI to its original mission — leading the intelligence community by fostering integration, collaboration and innovation.

Her allies argue that her outsider perspective will help modernize the intelligence community — though critics remain skeptical of her lack of traditional experience.

Thursday’s hearing will test whether Gabbard can win over skeptics — or if her controversial past will derail her bid to become the nation’s top intelligence officer.
