We'll just ignore the fact that there were other relatives of the young soldier in the car, and at least one has already come forward to confirm what the congresswoman said and added: "He was very disrespectful".
Trump since claimed to have contacted the families of all soldiers who died on his watch. The Washington Post called 13 of those families at random - and 7 confirmed having received some kind of communication from the white house (in 3 cases - just a letter, no call). So - he flagrantly lied yet again. Based on the WaPo's sample - he's barely done 50% of what he claims to have done.
In an even more bizarre twist he personally promised the father of another fallen soldier 25-thousand dollars (by his own account: it was to come from his personal funds). A weird response to a request to reform the bereavement fund. But then on top of it, Trump BROKE that promise. The father called him "a damn liar !". 
Sarah Huckabee Sanders responded by saying: "the cheque is in the mail". WTF ?
