Republican presidential candidate John Kasich sits down with 6abc Action News

PHILADELPHIA (WPVI) -- Republican presidential candidate John Kasich brought his campaign to Philadelphia once again Thursday, his second visit to Pennsylvania in two weeks' time.

His visit comes on the day he issued his harshest critique, yet, about his party's front-runner, Donald Trump, as Kasich predicts a contested convention is now unavoidable.

News anchor Brian Taff sat down with Kasich Thursday night at the Union League for an exclusive local interview.
