Former President Donald Trump heads to Ohio on Saturday for his first campaign-style rally since leaving the White House, an event that could signal how engaged he will be in next year’s congressional elections and possibly offer clues about whether he plans another presidential bid in 2024. Trump's event will mark his return to the kind of mass rallies that fueled his White House campaigns. Since he left office in January, Trump’s public appearances have been limited.

Phantom Fireworks, the nation's largest consumer-based retail fireworks company, is urging customers to shop early as the industry faces a potential shortage for the second year in a row. Last year, personal fireworks sales surged to record highs nationally.
