NEW: President Trump says gas prices are about to "tumble" in Alaska, then pins the threat of them shooting back up squarely on Democrats. "If the Democrats come along... the prices will double," the president warns as he touts a massive new Alaska energy project and predicts additional relief once the Iran war ends. Trump argues Democratic energy policies would reverse that progress and drive costs sharply higher, even warning of a "depression, recession, something very bad" if they return to power. ▻
