The U.S. Department of Homeland Security Secretary Kirstjyn Nielsen recently resigned. The besieged top person charged with protecting our borders often butted heads with President Trump and his desire to enforce tougher immigration.

“I hope that the next Secretary will have the support of Congress and the courts in fixing the laws which have impeded our ability to fully secure America’s borders and which have contributed to discord in our nation’s discourse,” Nielsen wrote in the two-page letter. “Our country — and the men and women of DHS — deserve to have all the tools and resources they need to execute the mission entrusted to them.”

What I find interesting is the timing of her resignation. It has been reported that Nielsen had no intention of quitting when she went to the meeting Sunday with the president and that she was forced to step down. The announcement of her departure came shortly after the meeting.

So why now? I wonder if Trump watched her interview with CNN’s Chris Como.

During the interview (which was not included by CNN in this clip), Como acknowledged the very difficult job border agents have and how he witnessed many of them showing compassion and working hard to keep everyone safe in the shelters. Como also pointed out how the current immigration laws often impede border agents from doing their job.

Nielson responded by thanking Como for recognizing the work being done and appreciated him making that point. She also agreed that immigration laws have to be improved to help solve this issue.

So was that the preverbal straw that broke the camel’s back? One has to wonder what Trump thought of his secretary appearing on CNN and thanking the host. The president and CNN have butted heads since he announced his candidacy and if history is any indication, it had to go over like a lead zeppelin.

Maybe it was time to for Nielson to go, but it sure seems like her CNN appearance did not do her any favors.
