The answer seems to be that Trump's "immigration week," which was to launch in Colorado and continue through Nevada and Oregon, developed a few glitches after his meeting with Hispanic leaders last Saturday.
The purpose, of course, was to convince Hispanic leaders that he, "The Donald," had a plan that would satisfy the Hispanic community as to his heart's desire to be fair and humane during his mass deportation of 12 million of their undocumented countrymen.
The problem that arose is that "The Donald" did not have such a plan nor did Kellyanne Conway have a clue how to manufacture such a plan out of thin air without making "The Donald" look like a pandering fool bent, using smoke and mirrors, on perpetrating another one of his scams on the Hispanic community. A community, BTW, he is on record as saying is low I.Q. and a threat to America's breeding population (or words to that effect).
Thus Kellyanne Conway, using her best robotic political face, was forced to say that the plan was "as yet undecided" ~ and indeed it was. Permanently, I suspect.
And "immigration week" went up in a puff of smoke.
