The UN migration agency's member states have rejected President Trump's nominee for director-general, making it only the second time in the agency's history that it will not be led by an American. During his presidential campaign, Trump called for a "total and complete shutdown of Muslims entering the United States".
An American has held the post on all but one occasion since 1951, but comments by Isaacs and Trump as well as administration policies surrounding immigration and refugees that have included a travel ban from several countries and the separation of children from parents requesting asylum may have hampered his chances.
US President Donald Trump speaks following a meeting on the South Lawn of the White House in Washington, DC June 1, 2018. Senegalese diplomat Youssoupha Ndiaye, upon leaving the voting in Geneva, said: "The American is out".

The IOM has been led by an American throughout its 67-year history with one exception, from 1961 to 1969.
Vitorino, who was selected by the dues-paying, ballot-casting members among the 172 countries in the IOM, will succeed longtime USA diplomat William Lacy Swing, who leaves in September.
An intergovernmental body that became a United Nations -related agency in 2016, IOM has had only one director-general who wasn't American since its creation 67 years ago.

"This IOM election really was not about Ken Isaacs, for whom I have a lot of respect as a humanitarian", Hetfield said.
The administration is fresh off major worldwide scorn over the separation of migrant families coming across the Mexico border.
Trump has also yanked the United States out of the Global Compact for Migration - a fact that several diplomats, who requested anonymity because they were not authorized to speak on the record about the balloting, cited as a worrying sign about USA policies on an issue that has vast implications around the world.
Mr Isaacs made his Twitter account private after his nomination for the IOM leadership in February led to criticism. After that Isaacs carefully stage-managed his media appearances and kept to script - with State Department handlers advising him or in tow.
But Trump's pick Ken Isaacs, an executive with the Christian charity Samaritan's Purse who faced serious charges of anti-Muslim bigotry, proved to be an untenable choice. Its work includes providing humanitarian aid to migrants, and helping track deaths of migrants across often deadly Mediterranean waters between northern Africa.
"Do they risk angering the Trump administration by rejecting its preferred candidate, or risk validating Trump's migration agenda by putting a Trump nominee in charge of IOM at the very moment his administration is attacking asylum in the USA?"
Playing in Isaacs' favor, along with the legacy of USA leadership, was money: The United States is traditionally the single biggest donor to the IOM, followed closely by the European Union.
