That’s how Bloomberg Businessweek describes the relatively high number of job vacancies within the Trump administration.

The White House has struggled to fill hundreds of critical political appointee positions in federal agencies, making it harder to advance the president’s agenda. From the Department of State, where no assistant secretaries and only a few ambassadors have been appointed, to the Department of Justice, where dozens of U.S. attorney positions remain vacant, Trump’s government has a skeletal feel as it heads into its sixth month. At the Department of Labor, the president has yet to fill any of the 13 senior positions that support Acosta. That includes the commissioner for the Bureau of Labor Statistics, the office tasked with tracking the number of job vacancies nationwide.

As of June 20, the Trump administration had filled 44 of the senior positions that require confirmation by the Senate, or less than 10 percent of the more than 500 openings, according to data compiled by the nonpartisan, nonprofit Partnership for Public Service. In contrast, Barack Obama had 170 positions confirmed at this point in his presidency, and George W. Bush had 130 filled.

The causes for the delay range from a chaotic period marked by the abrupt dismissal of transition chairman Chris Christie to concerns among potential appointees about working for an unpredictable boss. There’s also, as Trump called it in his May 11 interview with NBC News’ Lester Holt, “this Russia thing”—a broadening swirl of federal investigations casting a cloud of legal uncertainty over the presidency. “A few months ago, people might have been willing to say, ‘I still want a job, even if I don’t like Trump,’?” says Julian Zelizer, a presidential historian at Princeton. “My guess is there are more people now who are just not interested in being part of the chaos.”
