During the first 18 months, 27 Senate-confirmed officials have left their Trump administration jobs, per the analysis. On average, about 4.3 such officials departed during the first 18 months of the Bush, Obama and Biden administrations, which means that the Trump administration's second-term exodus is more than six times that average, the analysis noted. During Trump's first term, 11 Senate-confirmed officials left in the first 18 months. The analysis noted that one in nine such officials in Trump's second term has left their role, or about 11.4 percent. The average tenure of departed officials in Trump's second term was eight months. For 30 percent of departed officials, the wait for Senate confirmation was longer than their actual time in the job, per the analysis.
