Trump picks up endorsements from Pa. delegates

Donald Trump has picked up endorsements from 33 additional delegates in Pennsylvania, giving him a clear path to clinch the GOP nomination by the end of the primaries.

Trump now has a majority of the delegates awarded so far. He has to win just 48 percent of the remaining delegates to clinch the nomination and avoid a contested convention.

Trump won Pennsylvania, which guaranteed him 17 delegates. An additional 54 delegates were elected directly by voters - three in each congressional district. These delegates are free to support the candidate of their choice.

The Associated Press has confirmed that at least 33 of them plan to support Trump. They can, however, change their minds.

The AP delegate count:

Trump: 987.

Ted Cruz: 562.

John Kasich: 153.

Needed to win: 1,237.
