HARRISBURG, Pa. (AP) Republican Donald Trump has swept to victory in the Pennsylvania primary, while Democrat Hillary Clinton is also looking to Pennsylvania to pad her lead over Vermont Sen. Bernie Sanders.

The New York billionaire easily dispatched Republican rivals Ted Cruz and John Kasich in Pennsylvania, one of five Eastern states voting Tuesday.

Trump wins at least 17 of the state's 71 Republican delegates. The other 54 can vote for whomever they want at this summer's nominating convention, and it's not clear how many of them will wind up supporting the GOP front-runner.

All of the candidates spent time campaigning in Pennsylvania ahead of the primary.
