Jeff Zients arrived on Capitol Hill Thursday for a closed-door interview before the House Oversight Committee, as its inquiry into President Joe Biden's mental acuity nears its conclusion. The former White House chief of staff did not comment to reporters as he walked into the hearing room, exchanging a handshake with committee Chairman James Comer, R-Ky., before entering. The session was expected to run from about 10 a.m. into the afternoon, with Zients the last former Biden official expected to testify before the panel.

Comer has characterized Zients as a pivotal figure in the inquiry, saying he is 'one of the most, if not the most important, witnesses' in the case. The chairman asserted that Zients 'authorized the use of the autopen' and helped manage the final stretch of decisions that were signed into lawful but controversial pardons. The committee has been examining whether Biden or aides were truly directing clemency orders and other executive actions during the last months of his term, and whether those decisions were properly attributed given concerns about the president's cognitive condition. The interview adds to a series of high-profile testimonies from former Biden aides as lawmakers scrutinize late-term actions and the chain of command surrounding executive clemency.

The New York Times reported that Zients would have been among the top aides relaying Biden's clemency decisions to assistants, who drafted those orders before they were circulated back to Biden's senior officials and then given final approval. In that same coverage, Biden said he made every clemency decision on his own. Axios reported earlier this month that Zients signed off on pardons granted to five of Biden's family members less than 24 hours before he left office. The committee has emphasized its concern with whether the President’s office properly vetted and approved those actions in the context of public questions about presidential fitness late in Biden's term.

Zients' role has been described by lawmakers as central to the chain of command for Biden's autopen pardons. The panel has sought to determine whether decisions flowed from the President personally or through aides operating within a structured White House process. While presidents have historically used autopens to sign documents, Comer has argued the scope and timing of the pardons, particularly as concerns about Biden's mental acuity rose in the final year of his term, merit careful examination. The committee has also been collecting related records to assess whether any steps were taken to shield or obscure the decision-making process during that period.

Biden allies have pushed back on the investigation, denouncing the probe as politically motivated. They have argued that the Oversight Committee’s focus stretches beyond routine White House practice and veers into partisan territory. Still, Zients' testimony represents the latest step in a broader effort by Republicans to scrutinize White House operations late in Biden's term.

The interview of Zients comes as the committee moves toward concluding its examination of former Biden officials connected to the autopen and clemency process. Comer has signaled that the scope of the inquiry could touch on strategic communications and internal White House dynamics in the final months of Biden's presidency. As the last slated witness from the Biden White House, Zients's account could shape how lawmakers assess whether any senior aides played a role in decisions that should have rested with the President alone. Whatever the findings, the proceedings underscore the ongoing debate over presidential powers, executive actions, and the management of sensitive clemency decisions in the closing stages of a presidency.
