Who Issued This Directive?

A large number of Americans are angry about Obozo's flooding the field with Middle Eastern immigrants about whom the US knows nothing.

Bleating from Obozo and (R) politicians that stopping this flood is "un-American" or "not us" does nothing more than add fuel to the fire--which fire, I remind you, was one of the principal proximate causes of the Trump nomination.  (Do you hear that, Speaker Ryan?)

Anyhow, courtesy of Ticker, we see this:

...the Secretary of Treasury [State] and the Attorney General will invalidate all visas issued to Iranian citizens for future entry into the United States, effective today. We will not reissue visas, nor will we issue new visas, except for compelling and proven humanitarian reasons or where the national interest of our own country requires. This directive will be interpreted very strictly....

Is that also "un-American" and "not us"?

Tell it to Jimmy Carter, its author.
