What did Donald Trump do today?

He declared a non-urgent emergency.

This morning, Trump declared a national emergency with respect to the historically low and falling numbers of illegal border crossings into the United States. This would, if it survived any number of legal and procedural challenges, allow Trump to abate the "emergency" by reallocating money to build a border wall. 

Then, in a long and occasionally incoherent Rose Garden speech announcing the declaration, Trump said this of the "emergency" that he has been publicly musing about for months: “I didn’t need to do this."

Admitting that a national emergency isn't actually necessary is likely to hurt his chances of defending the declaration in court. 

Trump left directly from the announcement to spend the weekend at his Florida golf resort. Recently, Trump's resorts have been quietly firing the undocumented workers they illegally hired over a period of decades.

Why should I worry about this?

• National emergency declarations are for national emergencies.

• One way to decrease illegal border crossings is not to illegally offer undocumented immigrants work at your for-profit businesses.

• It is bad for the country if the president appears confused or unfocused in public.
