Last night on Late Night, Seth Meyers broke down the chaos that broke out following President Trump’s decision to implement a country-specific travel ban via executive order on Friday. Turns out, airports don’t do well with sudden changes to immigration policies, especially ones that roll in at the end of the work week.

Probably shouldn’t have been so surprised by the uproar; one of those moving walkways getting temporarily turned into a regular floor is enough to send most transportation hubs into total disarray.
