President Donald Trump's claim that he personally contacted nearly every family of an American service member killed since taking office is facing serious questions after newly disclosed Pentagon correspondence revealed that the White House was still scrambling to identify those families.

According to an investigation published Friday by Roll Call, White House officials urgently requested the names and contact information of fallen service members' relatives just hours after Trump publicly claimed he had already contacted virtually all of them.

The revelation raises questions about the accuracy of the president's statements during an increasingly contentious dispute over his treatment of Gold Star families.

The Pentagon Emails

On October 17, Trump told Fox News Radio that he believed he had contacted virtually every family that had lost a service member during his presidency.

But around 5 p.m. that same day, White House officials were requesting an updated list from the Pentagon.

Capt. Hallock Mohler, an aide to Defense Secretary James Mattis, provided information identifying fallen service members, the circumstances of their deaths, and contact information for surviving relatives.

The email exchange indicates that the administration did not yet possess the complete information necessary to support Trump's public claim.

An Associated Press investigation further complicated the president's account. Of 20 military families contacted by the news organization, half reported that they had not heard from Trump.

Controversy Over a Fallen Soldier's Widow

The disclosures come amid a separate controversy involving Army Sgt. La David Johnson, one of four American soldiers killed in an October 4 ambush in Niger.

Florida Democratic Rep. Frederica Wilson, who was present during Trump's condolence call to Johnson's widow, Myeshia Johnson, accused the president of making an insensitive remark about the soldier's death.

Wilson said Trump told the grieving widow that her husband knew what he had signed up for.

Trump disputed Wilson's account, while White House Chief of Staff John Kelly defended the president during an emotional press briefing Thursday.

The disagreement has become a national controversy over how the commander in chief communicates with families who have lost loved ones in military service.

White House Defends the President

White House Press Secretary Sarah Huckabee Sanders insisted Wednesday that Trump had contacted all families whose information had been provided through established White House military procedures.

On Friday, White House spokesman Raj Shah reiterated that the administration had ensured contact with families of service members killed in action who had been identified through existing protocols.

However, the Pentagon correspondence suggests the White House was still gathering the information necessary to reach additional families after Trump's public statements.

A Question of Presidential Credibility

Presidents have long offered condolences to families of fallen service members, although no law requires them to personally telephone every family.

The newly disclosed correspondence does not establish that Trump deliberately misled the public. It does, however, contradict the impression that his outreach to military families was nearly complete.

For the families of fallen American service members, the controversy has placed their private grief at the center of a national political dispute.

And for the White House, the Pentagon emails create a new question: Why did the administration need an urgent list of Gold Star families after the president claimed he had already contacted virtually all of them?
