Donald Trump will not be inaugurated as the 45th president of the United States until January 20, 2017, but that isn't stopping the president-elect from selling "President of the United States of America - Trump / Pence" stickers, t-shirts and buttons. The presidential products have similar descriptions, but all of them say "Show your support for the 45th President of the United States, Donald J. Trump."
The "President of the United States" merchandise is distinct from the "president-elect" merchandise that the Trump Campaign also began selling post-election. Notably the "President" t-shirt says "2016" even though Trump will not assume the title until next year.
The Trump is also selling the "Official USA 45th Presidential Hat":
Although the hat is marketed as the "Official USA 45th Presidential" hat, the funds will fund Trump's campaign, not the USA.
The president-elect's transition team did not respond to a request for comment on Trump's apparent trading on the office of the president for financial gain.
