New Delhi, April 17 -- US President Donald Trump addressed his viral promotion involving McDonald's and admitted it was embarrassing. Trump gained mixed reactions on the internet when a delivery person donning a "DoorDash Grandma" shirt reached the Oval Office to promote his "no tax on tips" law. He received two bags of McDonald's, his long-time favourite fast food and handed over a $100 tip.

On Thursday, Trump attended a roundtable event in Las Vegas, Nevada. At the event, he opened up about the DoorDash promo idea, saying, "To be honest, it was a little tacky."

"You know, they come up with these crazy ideas ... They're a little embarrassing," he added.
