Donald Trump has had a pattern of contempt for those who serve, calling America's war dead "losers" and the Marines killed at Belleau Wood "suckers."

"I don't think about Americans' financial situation," Trump told reporters on the White House South Lawn before boarding a flight to China for meetings with President Xi Jinping. "I don't think about anybody. I think about one thing: We cannot let Iran have a nuclear weapon. That's all."

More than a year and a half into his second term, President Donald Trump is struggling to win over the American public — a new war, rising prices at the pump, and growing unease among his own voters are making that task harder by the day.
