Agents at Immigration and Customs Enforcement are under increasing pressure to boost the number of arrests and deportations of undocumented immigrants, as President Donald Trump has expressed anger that the amount of people deported in the first weeks of his administration is not higher, according to three sources familiar with the discussions at ICE and the White House.

A source familiar with Trump's thinking said the president is getting "angry" that more people are not being deported and that the message is being passed along to "border czar" Tom Homan, Homeland Security Secretary Kristi Noem, White House Deputy Chief of Staff Stephen Miller and acting ICE Director Caleb Vitello.
