In the hours after President Donald Trump said on an Oct. 17 radio broadcast that he had contacted nearly every family that had lost a military servicemember this year, the White House was hustling to learn from the Pentagon the identities and contact information for those families, according to an internal Defense Department email.

The email exchange, which has not been previously reported, shows that senior White House aides were aware on the day the president made the statement that it was not accurate — but that they should try to make it accurate as soon as possible, given the gathering controversy.

Not only had the president not contacted virtually all the families of military personnel killed this year, the White House did not even have an up-to-date list of those who had been killed.
