Donald Trump speaks to Fox News (screen grab)

Donald Trump celebrated reaching the numerical threshold for the Republican presidential nomination on Thursday with a short video trolling both President Barack Obama and many conservative figures.


The video, posted on his Instagram account, features Jeb Bush, Sen. Ted Cruz (R-TX), Ohio Gov. John Kasich -- each of whom failed to stop Trump from prevailing in the 17-person GOP race -- predicting that Trump would not win.

It also shows ABC News host George Stephanopoulos, who pressed Trump earlier this month regarding his tax returns.

The clip can be seen below.
