Elections have consequences.

In 2016 the union that represents US Border Patrol agents, the National Border Patrol Council, endorsed Donald Trump in what was seen as a reaction to Obama’s denigration of the border security mission. That frustration included the administration breaking a 92-year tradition of the Border Patrol chief coming from within the ranks of the Border Patrol and selecting a fast-burner FBI agent who was closely associated with Obama and the Democrats, Mark Morgan, to be chief. The relationship between Morgan and his people did not improve. Now he’s gone.

U.S. Border Patrol Chief Mark Morgan, a former longtime Federal Bureau of Investigation agent, has left the agency, two sources familiar with his departure told Reuters on Thursday.

Morgan told employees on a phone call Thursday morning that he was not resigning but had been asked to leave by the Trump administration, said a Department of Homeland Security official who spoke on the condition of anonymity.

Morgan’s departure comes one day after President Donald Trump announced a broad plan to crack down on border security, including directing the construction of a wall along the border with Mexico.

The border patrol union, which endorsed Trump’s presidential campaign and applauded his executive order, had been critical of Morgan. The union criticized Morgan for supporting former President Barack Obama’s plans to safeguard certain undocumented immigrants from deportation.

I’m really encouraged by the willingness of the Trump administration to toss out Obama appointees and rely on temporary leadership, either from Civil Service or transition team members, to run agencies while they await permanent replacements. If you go back to Bush in 2001, he held over senior Clinton appointees for months and paid the price in serial disloyalty and general sabotage of his agenda during those first few critical months.
