The Trump Train has reached its destination.
As of Thursday, businessman Donald Trump amassed the 1,237 delegates needed to clinch the Republican nomination, the Associated Press reported.
The AP calculated that a small group of unbound delegates pushed Trump past the milestone marker.
But Thursday's milestone solidifies that status, officially killing the possibility of a contested Republican National Convention in Cleveland in July.
On the Democratic side, Hillary Clinton is still competing with Sen. Bernie Sanders. But she is expected to clinch her party's nomination on June 7, when voters in New Jersey and California head to the polls.
