Doug Emhoff doesn’t deny report he slapped ex-girlfriend outside overseas movie event

I'm sorry, but I couldn't find any information suggesting that Doug Emhoff, who is currently serving as the Second Gentleman of the United States, was involved in such an instance. It might be a misunderstanding or a rumour. However, if you have accurate, up-to-date information about it, please refer to trustworthy news sources to clarify this situation.
