The Trump administration is experiencing an unprecedented number of vacancies in Senate-confirmed positions, raising concerns about potential delays in advancing its policy agenda as Republicans face the possibility of losing control of the Senate in upcoming midterm elections. According to data from the Partnership for Public Service, a nonprofit organization tracking presidential appointments, the current level of vacancies is the highest since the Reagan administration.

This trend stems from a combination of factors, including high turnover, slower confirmation processes, and numerous nominations withdrawn at the White House’s discretion. Administration officials and allies, who spoke anonymously to discuss internal dynamics, described a personnel system that has shifted in the second year of the presidency toward more thorough vetting of candidates, prioritizing caution over speed. This approach aims to reduce risks but has also slowed the pace of nominations and confirmations.

“The vetting has to be higher and more thorough,” said Trent Morse, former deputy director of personnel during the transition and early months of the administration. He noted that while the administration initially pushed to confirm a large number of appointees rapidly, it has since transitioned to a “maintenance phase” requiring greater scrutiny. Personnel director Dan Scavino and his deputy Morgan Dewitt have been credited by several administration officials for managing this complex and evolving process.

Recent setbacks have highlighted the importance of rigorous vetting. Earlier this month, Katie Zacharia, appointed by President Trump as White House press secretary without personnel office involvement or extensive background checks, resigned after only five days amid questions about her qualifications. Additionally, the U.S. ambassador to Greece was asked to step down following allegations of misconduct.

Despite these challenges, many officials voiced concern that the administration is missing opportunities to fill key roles in national security, immigration, economic policy, and energy departments while the Senate remains Republican-controlled. Some officials pointed to heightened caution and fear of scrutiny as contributors to the slow pace of nominations. One official described the environment as one in which the tendency is to avoid risk altogether, noting that mistakes in staffing invite intense criticism.

The White House defended its personnel team, with Chief of Staff Susie Wiles praising Scavino as a trusted adviser whose experience is vital to the administration’s operations. Cabinet members echoed this sentiment, emphasizing the importance of selecting candidates aligned with the administration’s goals, even if the process takes longer. Pete Meachum, chief of staff at the Department of Transportation, emphasized the value of “the right person rather than the person fast.”

The administration’s first year demonstrated a robust hiring effort, with 452 Senate-confirmed appointments—more than any comparable period in recent decades. However, nomination submissions have slowed considerably since 2025. Only 186 nominees have been put forward so far this year, far fewer than in the previous administration, according to Partnership data. This slowdown persists despite a Senate procedural change in late 2025 intended to facilitate quicker confirmation votes through “en bloc” consideration.

The Senate’s reduced session days this year have also limited opportunities for confirmation votes, with the most recent group of nominees confirmed in August. The White House anticipates submitting another package of nominees soon. Currently, approximately 249 Senate-confirmed roles remain without nominees, and dozens more await Senate action.

Some nominees have faced extended confirmation delays. For example, Austin Dahmer, nominated in 2025 for a senior Defense Department position, has waited over a year, facing tough questioning from senators across party lines.

Administration officials pointed to instances of rapid confirmation when urgency demands, citing the swiftness of hearings for Director of National Intelligence appointee Jay Clayton and Homeland Security Secretary Markwayne Mullin. Still, the average confirmation period has lengthened since the beginning of Trump’s tenure, complicating efforts to fully staff the government.

President Trump has expressed a preference for appointing individuals to “acting” roles to maintain flexibility and speed, but these positions carry legal restrictions and can hamper long-term policy implementation. The personnel office led by Scavino and Dewitt operates with regular communication with agency leaders and adapts to evolving demands by working from multiple White House locations.

Going forward, fears persist that a shift in Senate control following the midterms could further hinder confirmation processes. The so-called “lame duck” period is historically challenging for nominees, as Senate negotiations and holds on confirmations intensify. Experts warn that if Republicans lose the Senate majority, the delays and vacancies may worsen, potentially impeding the administration’s ability to staff critical government positions during its next term.
