Daniel Foote, the U.S. special envoy to Haiti, resigned on Thursday (Sept. 23) protesting the government’s “inhumane” treatment of Haitian and other migrants at the Texas border.

Foote was just appointed to the position by the Biden administration this July, the Associated Press reports, after Haitian President Jovenel Moïse was assassinated. However, two U.S. officials told the outlet, he became quickly “frustrated” with the government’s “lack of urgency” in improving conditions in the Caribbean country.

“I will not be associated with the United States inhumane, counterproductive decision to deport thousands of Haitian refugees and illegal immigrants to Haiti, a country where American officials are confined to secure compounds because of the danger posed by armed gangs to daily life,” Foote wrote to Secretary of State Antony Blinken in his resignation letter.

“Our policy approach to Haiti remains deeply flawed, and my policy recommendations have been ignored and dismissed when not edited to project a narrative different from my own,” he added.

Foote confirmed he was stepping down from the position effective immediately “with deep disappointment and apologies to those seeking crucial changes.”

The change in personnel arrives amidst the United States’ accelerated expulsion efforts and allegations of border patrol misconduct. As reported by REVOLT, the Department of Homeland Security is currently investing disturbing footage of agents harassing migrants after an influx of people arrived at the U.S.-Mexico border last week.

According to AP, the makeshift encampment under the Ciudad Acuña, Mexico and Del Rio, Texas international bridge – which at one time hosted over 14,000 people – has shrunk considerably in recent days. On Sunday (Sept. 19), the U.S. carried out 10 expulsion flights back to Haiti, Haitian officials confirmed. This week, expulsion efforts have continued with seven flights per day, AP writes, marking one of the United States’ largest expulsion efforts in decades.
