Trump's polemica, spoke tactfully to the soldier's vein

The latter claims to have heard the comments made on the phone while in a car with the army's family killed, David Johnson.

A White House official reacted by saying that conversations with Washington's number one family members were private.

The 25-year-old was among 4 soldiers killed on 4 October, in an area where Islamic State militants and al-Qaeda fighters operate. His wife is awaiting the couple's third child.

In an interview for CNN, lawmaker Wilson confirmed that the phone call with Trump had taken place before Johnson's coffin arrived in Miami.

Everyone knows that when they go to war they may not come back alive, but telling a widow is insensitive”, it was Congressman's words.

The complete context of the conversation is not yet known. Wilson said that when he asked Miss Johnson for more details, she had replied that she did not remember. The alleged comments prompted harsh reactions on social networks, with congresswoman saying Trump had no character, empathy or grace to be president of the United States.

The American president has been criticised for not having contacted the families of four soldiers killed shortly after the event. On Monday, he said that he had written letters to relatives and that he would call them very soon.

To counteract the charges, the American leader suggested that his predecessor, Barack Obama, had not called his cabinet chief's family, John Kelly, when his son was killed in Afghanistan in 2010.
