A month after Donald Trump won the US presidential elections, his staff requested that the Pentagon send across photographs of military tactical vehicles that could be used in his inaugural parade, according to e-mails newly-obtained by The Huffington Post.

The e-mails were released in response to a Freedom of Information Act request and show that despite previous denials, the Presidential Inaugural Committee was “seriously considering adding military vehicles to the Inaugural Parade,” a Pentagon official wrote in an internal e-mail dated Dec. 13, 2016.

The e-mail sender, whose name has been redacted, wrote: “The conversation started as ‘Can you send us some pictures of military vehicles we could add to the parade.’

“I explained that such support would be out of guidelines, and the costs associated with bringing military vehicles to the [National Capital Region] would be considered reimbursable,” the author added.

Wednesday’s Huffington Post article was a follow-up to a piece published in January titled “Trump Sought Military Equipment For Inauguration, Granted 20-Plane Flyover.”

In it, a source involved in the parade planning told the website that “they were legit thinking Red Square/North Korea-style parade.”

The Pentagon is known to work with presidential inaugural committees to plan the parades but this support is usually limited to musical groups rather than military equipment, The Huffington Post reported.

According to the news website, a Trump aide had issued an off-the-record denial in December that there were ever any plans to use military hardware during the parade. The Huffington Post adds, however, that it is not clear whether the aide was aware of the e-mails sent to the Pentagon.

The author of the released e-mail seems uncomfortable with the request.

“I’m extremely reluctant to produce an improvised list of military vehicles that we might be held to,” the Pentagon official wrote.

“Also concerned that we as a command need an opportunity to staff this request and to make deliberate decisions about vehicle choice and configuration, paint scheme, uniform for crew members, etc. before we start providing pictures which might be regarded as binding.”

Ultimately, Trump’s staff did not form a formal request for military vehicles and instead asked for a flyover of fighter aircraft, which was granted but canceled due to bad weather conditions.

In response to an e-mail stating that the Trump team would not be procuring “military tactical vehicles” for the parade, a Pentagon official wrote “great news” in a Dec. 27 e-mail.
