The House Oversight Committee is hearing from two top former Biden administration aides this week as Republicans continue to probe allegations that ex-President Joe Biden's top lieutenants covered up the former leader’s mental decline while in office.

Former Domestic Policy Council Director Neera Tanden will meet with the committee on Tuesday, and former Assistant to the President and Senior Advisor to the First Lady Anthony Bernthal will meet with the committee on Thursday.

The committee also has interviews scheduled with former administration officials Annie Tomasini and Ashley Williams, while seeking interviews with several officials in the Biden inner circle, including former Chief of Staff Ron Klain and former Senior Advisor to the President for Communications Anita Dunn. 

Biden’s former doctor, Kevin O’Connor, will sit down with House investigators in July.

House Oversight Committee Chair James Comer, R-Ky., is probing whether those closest to Biden in his White House knowingly colluded to hide the former president's declining mental acuity and used methods to circumvent the former president when it came to the issuance of important orders.

President Donald Trump also ordered the Department of Justice to open an investigation into the matter. The president directed Attorney General Pam Bondi and White House counsel David Warrington to handle the investigation.

In response to the Trump administration's call for an investigation, Biden declared he was the only one who "made the decisions" during his presidency and called Trump's efforts a "distraction."

Among the questions House investigators are expected to have is whether any Biden officials used the autopen to authorize executive actions without the president's permission. 

The sit-downs are behind closed doors, as opposed to public congressional hearings.

The interviews will be transcribed and likely released at a later date.

Comer previously told Fox News Digital that the more muted setting of a closed-door interview would allow House lawmakers to get more key information, as opposed to the public spectacle of a hearing.

"I’ve studied history, there’s never been a committee hearing that did what it’s supposed to do," Comer said.

"But these depositions and interviews, do. You’ve got one hour, you’re not interrupted, you don’t have to go five minutes back and forth. So to extract information, we’re going to go with the interviews. We could have a hearing later on, but right now, I think we can get more done quicker with interviews."

In a historic turn of events, Iran agreed to a ceasefire Monday following a limited strike on a U.S. military base in Qatar. 

The agreement, brokered by President Donald Trump, marks a dramatic de-escalation after 12 days of war.

Even as the ceasefire deal seems to be teetering, experts say Iran’s decision to step back reflects the heavy toll its military infrastructure has taken in the wake of coordinated U.S. and Israeli strikes on nuclear sites, missile stockpiles and key production facilities.

"Iran cannot win this war," said Danny Orbach, a military historian at Hebrew University. "They’ve lost roughly 60% of their launchers. Even if they still have around 1,000 long-range missiles, without enough functioning launchers, they can’t deploy them effectively."

According to U.S. and Israeli officials, the attack on the Al Udeid Air Base in Qatar — the largest U.S. base in the Middle East — caused no casualties and only minor damage. The strike appears to have been carefully calibrated.

"The strike in Qatar was coordinated with the Americans and was not intended to impress or cause real harm," claimed Sima Shine, a former Mossad official and senior Iran expert at Israel’s Institute for National Security Studies. "Iran still has weapons, but it doesn’t want to draw the U.S. into an all-out war. And they know closing the Strait of Hormuz will end badly for them."

"What has largely remained intact is Iran’s short-range capability," said Blaise Misztal, vice president of policy at the Jewish Institute for National Security of America (JINSA). "These are thousands of rockets, missiles, and drones that can’t reach Israel, but can absolutely hit U.S. bases in Qatar, Iraq, Bahrain, and the UAE. That’s what we saw in the strike on Al Udeid."

Misztal added that Iran’s remaining arsenal is "well-developed and available in far greater quantities" than its long-range weapons. "The danger isn’t just to U.S. forces. Iran can still target energy infrastructure, major cities, and commercial shipping across the Gulf."

TRUMP HAILS ‘MONUMENTAL' DAMAGE AS EXPERTS AWAIT VERDICT ON IRAN’S NUCLEAR PROGRAM

In a 2024 report for JINSA, retired General Frank McKenzie, former commander of U.S. Central Command, warned that American bases in the Gulf are critically vulnerable to Iranian missile and drone saturation attacks. He noted that installations like Al Udeid are just minutes from Iranian launch sites, leaving little time to react — and called for a strategic shift westward and stronger missile defense integration with regional allies to overcome the "tyranny of geography."

As the U.S. repositioned some aircraft and ships ahead of the expected Iranian retaliation, Chairman of the Joint Chiefs of Staff Gen. Dan Caine confirmed that defense measures had been bolstered across Iraq and Syria.

Analysts say the real reason for Iran’s climbdown is the sheer scale of its losses. 

Orbach explained that Iran is now facing what military theorist William Tecumseh Sherman once described as "a range of bad choices." "They don’t have the money to rebuild everything," he said. "They’ll have to choose between restoring their missile program, supporting proxies, or reviving their nuclear infrastructure. They can’t do it all."

"Iran remains the world’s leading state sponsor of terror," Misztal added, "They’ve plotted assassinations on U.S. soil before. They’ve carried out attacks globally," Misztal said. "And they’ve invested heavily in cyber since the Stuxnet attack in 2010. Energy infrastructure, regional systems, even U.S. targets — they’re all vulnerable."

"Will Iran learn enough of a lesson from these attacks to moderate its behavior? It seems unlikely," Misztal added, "I think their hope is that, regardless of how this ends or what happens to their nuclear program, they can return to their usual pattern of aggression — using proxies and indirect attacks throughout the region and beyond. This regime is built on ‘Death to America, Death to Israel.’ That hostility is central to its identity, and it can’t abandon it without losing legitimacy."
