It would be easy to assume famed business man turned President of the United States Donald Trump would be good at hiring and retaining qualified personnel to help run the third branch of our government — the executive branch. He is, after all, a self-proclaimed genius. Moreover, voters were told during the presidential campaign that Trump would hire the best and most qualified people for available positions.

We are now a year and two months into the Trump administration and each passing week presents a new, high-level staffing change which shakes up not only the White House and executive departments, but our whole government as well.

Politifact is reporting that 43 percent of Trump’s senior staffers had left, or were forced to leave, their positions since he took office over a year ago. That number is speculated to rise in the coming weeks as Trump noted, “…we’re getting very close to having the Cabinet and other things that I want.” This raises an important question: Who must be replaced for Trump to go from being “very close” to having exactly who he wants in his cabinet?

Let’s ponder the implications of Trump’s recent cabinet change with his decision to fire, now former, Secretary of State Rex Tillerson via Twitter. The State Department, for example, has 28 ambassadorships, nine assistant secretary openings, three UN representative spots and three undersecretary positions without nominations to fill the posts.

What’s more, several countries without permanent ambassadors are our allies and partners in securing peace around the globe. These include, but are not limited to, South Korea, Turkey, Saudi Arabia, Jordan, Egypt and Qatar. How is the U.S. expected to maintain and build upon its diplomatic record when key positions are left vacant? Even senior advisor Jared Kushner is limited now in his Middle East diplomacy work since his security clearance was downgraded late last month.

The rapid turnover in key policy and administrative positions like secretary of state, director of the FBI, White House communications director and economic adviser leaves lower staff without continuity and leadership.

President Trump, like all other presidents before him, is but one person. We will not progress into a brighter future due to some singular executive tweeting policy decisions at a whim. Rather, it will take what has worked in the past—a diverse group of patriotic career government officials working together for the common good of our people.
