Four high-profile ex-Biden officials, including Karine Jean-Pierre, to appear in closed-door House Oversight interviews.

Key Former Biden Officials Scheduled for House Committee Testimony

Former White House press secretary Karine Jean-Pierre is among four top Biden administration aides slated to give closed-door testimony before House Oversight Committee investigators in September, according to committee sources. The planned interviews mark a significant escalation in the committee’s ongoing probe into alleged efforts to conceal signs of President Biden’s mental and physical decline while in office.

Committee Chair James Comer, R-Ky., is leading the investigation, which seeks to determine whether any executive actions were approved using autopen without the president’s full knowledge and if former aides participated in covering up Biden’s health status. The White House and Biden’s allies have strongly rejected the allegations, maintaining that all decisions were made personally by the president. In an interview published Thursday, Biden himself asserted, "I made every decision on my own."

Testimony Timeline and Broader Investigation

In addition to Jean-Pierre, three other high-profile former officials are scheduled to appear: Ian Sams, former special assistant and senior White House counsel advisor; Andrew Bates, former deputy assistant and senior deputy press secretary; and Jeff Zients, former White House chief of staff. The committee confirmed their voluntary, transcribed interviews are set for the coming weeks, with Jean-Pierre on September 12, Sams on August 21, Bates on September 5, and Zients on September 18.

The list of witnesses also includes both former Biden chiefs of staff, with Ronald Klain expected to participate in a separate interview later this month. Previously, four ex-Biden aides—including ex-White House physician Kevin O’Connor and long-time Jill Biden adviser Anthony Bernal—have spoken to the committee, with both O’Connor and Bernal invoking the Fifth Amendment but denying any admission of wrongdoing.

Former deputy White House chief of staff Annie Tomasini is also due to testify after being subpoenaed at her counsel’s request. Most interviews and depositions are expected to be staff-led, though committee chair Comer and other members have attended some sessions. Rep. Jasmine Crockett, D-Texas, has appeared unexpectedly at each of the last three interviews, providing additional scrutiny.

Amid mounting political tension, Rep. Byron Donalds, R-Fla., has called for the committee to subpoena Jill Biden following Bernal’s testimony, intensifying partisan rhetoric around the investigation.

While the committee’s Republicans describe the probe as necessary oversight, a source close to the Biden team characterized the investigation as “dangerous” and politically motivated. The source argued that Republicans are searching for minor inconsistencies to justify further legal action by the Justice Department, fueling what they describe as a campaign of political retribution.

The testimony of these key figures is expected to play a central role in determining whether allegations of cover-up and improper delegation of presidential authority are substantiated, with potential implications for future congressional oversight and executive accountability.
