The Department of Homeland Security announced Monday it would end a program giving Venezuelan migrants special status.

The Trump administration’s decision Sunday to end the protection from deportation for hundreds of thousands of Venezuelans living in the United States is based on the notion that conditions have improved in the South American country to the point that its citizens no longer need to be safeguarded from a repressive dictatorship.

Richard Grenell, the envoy for special missions, said he was flying home with the detainees after he met with President Nicolás Maduro.
