Psaki defended Biden’s lack of any public comments against recent footage of Texas Border Patrol agents using long horse reins to move crowds of immigrants.

“His actions make clear how horrible and horrific he thinks these images are,” she said, responding to questions from PBS NewsHour White House Correspondent Yamiche Alcindor.

She argued that the administration has already made a policy change in response to the Haitian migrant situation: Border Patrol agents have been suspended from using horses in Del Rio, Texas.

Psaki held the briefing the same day the Biden administration’s special envoy to the country resigned, protesting large-scale expulsions of Haitian migrants to their homeland.

Daniel Foote was appointed to the position in July, following the assassination of Haiti’s president. He submitted a letter of resignation Thursday protesting what he called “inhumane” deportations. He also criticized the U.S. statement of support for the unelected, de facto Prime Minister Dr. Ariel Henry over an earlier accord “shepherded by civil society.”

“The hubris that makes us believe we should pick the winner — again — is impressive,” the letter reads.

Alcindor asked if the administration has a response to this criticism.

“We support a Haitian-led process,” Psaki said. “We don’t back any one political group and we continue to encourage all political stakeholders to engage in dialogue.”
