President Donald Trump warned Honduran President Juan Orlando Hernandez that Washington will cut aid to Tegucigalpa unless a Honduran migrant caravan traveling north through Mexico is stopped and turned around.

“The United States has strongly informed the President of Honduras that if the large Caravan of people heading to the U.S. is not stopped and brought back to Honduras, no more money or aid will be given to Honduras, effective immediately!” Trump wrote on Twitter on the morning of Oct. 16.
