this story is just made up.
................
lets review the numbers
Trump has 670/680 delegates or so.
there are 846 bound delegates, yet to be chosen.
magic number is 1237.
or not, please correct any errors, thanks
The fivethirtyeight blog (Nate Silver, I believe) has the current assigned delegate count at 691, or 10 to 20 more than your source. (This may be due to winning Congressional District based delegate assignments from Missouri’s Tuesday election.)
It puts Trump at 96% of where he theoretically should be at this point in the race. All other candidates are far, far away from their targets.
