President-elect Donald Trump said Monday that his incoming administration is “looking at” privatizing the United States Postal Service, which has been notoriously unprofitable.

The plan is not a new one for Trump, who floated a similar restructuring during his first term in the White House. He has not taken a firm stand on overhauling the institution that is older than the country itself, but he said Monday that it was “not the worst idea I’ve ever heard.”
