At a rally in Ashburn, VA on August 2, a veteran gifted his Purple Heart to GOP presidential nominee Donald Trump. Trump, who received five draft deferments during the Vietnam War, recounted the story to the audience, who at first found it touching. However, Trump once again set himself up for a day of media difficulty with his next joke, "I always wanted to get the Purple Heart. This was much easier." He then appeared to pause for a laugh that did not come.
Trump has recently been in the news for feuding with the parents of a Muslim soldier who was posthumously awarded the Bronze Star and a Purple Heart in Iraq. While such an offer of someone's military medal is not unheard of, American politicians are generally expected to demur and decline out of respect for what actually goes into getting a Purple Heart.
Following the joke, Trump did invite Lt. Colonel Louis Dorfman on stage to a crowd chanting "USA!" which was, admittedly, a nice moment. Trump should probably leave the jokes to the comedians, but not having experience in an area has never stopped him before.
