President Donald Trump has acknowledged the impact of the United States’ attack on Iran and a sharp rise in prices on stunning Republican losses in midterm elections on Tuesday, but said the move was justified and denied responsibility for the rout. “We actually have the greatest economy, but because of the gasoline price, people don’t see it as much as they would have without it. And the gasoline was caused by Iran,” he told Fox News in a televised phone interview late on Tuesday.
