It’s hard to beat Reagan; the Senate confirmed most of his Cabinet within two days of his inauguration, records show. Bill Clinton also had a relatively easy time, clearing most of his picks within a week with the support of a Democratic Senate. The exception was Janet Reno, the first woman to serve as attorney general; she was confirmed almost two months later, after two other candidates dropped out amid “nanny issue[s].”

Trump’s progress tracks more closely to that of George H. W. Bush and Obama, both of whom saw protracted opposition to their nominees and multiple dropouts. Here’s how quickly each administration filled its Cabinet after Inauguration Day:

The elder Bush had to contend with a Democratic Senate eager to rein in a Republican president after eight years of Reagan. His biggest headache was the nomination of John Tower for defense secretary, which the Senate eventually voted down along party lines, a rather rare outcome. (Tower’s replacement? Dick Cheney, the future vice president.)

Obama also struggled to round out his team, even though he had the backing of a Democratic majority in the Senate. The core of his Cabinet was in place within a week, many with near-unanimous support—including Hillary Clinton as secretary of state. But he ran into trouble with his nominee for secretary of labor, then-Representative Hilda Solis; Republicans stonewalled her over her past support for pro-union legislation, before eventually acquiescing.

Obama also struck out twice with his commerce nominees, dropping New Mexico Governor Bill Richardson amid a federal investigation into political contributions and losing Republican Senator Judd Gregg over “irresolvable conflicts.” Secretary of Health and Human Services Kathleen Sebelius was the last Cabinet member to be confirmed, almost 100 days after Obama took the oath of office.

Trump, however, is in a different league. So far, all of his nominees who’ve gone up for a Senate vote have been OK’d by the body—though Betsy DeVos, who needed Vice President Mike Pence’s tie-breaking vote to take her seat as secretary of education, came closest to failing. But after more than two weeks, still less than half his Cabinet is in place. In every day of his administration so far, his boardroom has had the lowest occupancy rate of any presidency in the past three decades.

He blames Democratic opposition, which has certainly been stiff. Only a handful of Democrats have supported a majority of his nominees, and several voted against nearly all of them. Democratic leaders have also fought against quick votes, requiring the full 30 hours of debate for most of Trump’s picks and slowing consideration to a relative crawl.

In response, Senate Majority Leader Mitch McConnell released a statement on Tuesday, decrying Democratic delay: “We’ve seen unprecedented obstruction from our colleagues across the aisle. … It’s made the confirmation of this president’s nominees the slowest in modern history.”
