HARRISBURG, Pa. (AP) — Facing the need to win Pennsylvania, Vice President Kamala Harris has sworn off any prior assertion that she opposed fracking. But that hasn’t stopped Republican Donald Trump from wielding her now-abandoned position to win over working-class voters in the key battleground state where the industry means jobs. Last week, in his first appearance in Pennsylvania since Harris became the Democrats’ presumptive nominee, Trump repeatedly warned that Harris would ban fracking and devastate the economy in the nation’s No. 2 natural gas state. Harris called to ban fracking as a presidential primary candidate in 2019.
