When they can no longer use normal means to communicate, they used HAM.

After finding out that the NSA also survails radio frequencies, they needed a new (old) covert way to communicate - Bird Comms.

> Messenger birds have been used throughout history to communicate; people like the Rockefellers have used carrier pigeons to carry sensitive financial information, and great commanders such as Alexander the Great and Julius Caesar used pigeons to communicate across their vast empires. Both sides of WW1/2 maintained large pigeon corps. UK alone said to have engaged some 200,000 pigeons during WW2.

Could this explain Trump's bird comms?

Have they been using messenger birds to circumvent survaillance?

Is Trump telling them/us that he knows they're doing so, by using the bird comms about Nikki and Ron?
