Trump is becoming 'increasingly unhinged about border crisis' and 'making impossible requests': report

President Donald Trump has become reportedly "increasingly unhinged" when it comes to his manufactured border crisis, a senior White House official has told CNN.

In a conversation with White House correspondent Jim Acosta, by the time Kirstjen Nielson announced her resignation Sunday, she was "tearing her hair out" with the demands of the White House.

National security analyst Juliette Kayyem echoed the same sentiment, saying that it won't matter who Trump ultimately appoints to head the Department of Homeland Security, they will be set up to fail.

On Friday, CNN's Jake Tapper said that Trump told border patrol officials that they were ordered to stop entrances to the United States, which violates U.S. law.

CNN host Ana Cabrara read a statement from a senior White House official who noted the president seems to be losing it over his non-stop fight with the border.

Nielsen "believed the situation was becoming untenable with the president becoming increasingly unhinged about the border crisis and making unreasonable and even impossible requests," CNN reported Sunday.

Acosta confirmed it's in line with what he's hearing from his sources.
