You are over thinking things.
What is obvious is that children love teddy bears, and Ted enticed them, and their parents, and other parents in Mexico who saw that on TV, that ‘we’ welcomed them into our country.
Notice he no longer does that?
Even Ted sees the obvious.
Ted enticed them?
LOL
Ted gave them teddy bears and told them to leave. He then went back to Washington to write two bills, one repealing Obama's DACA and the other to block Obama's DACA expansion.
BTW, here's your guy Donald meeting with the Dreamers.
