That is an article where a guy is certainly trying to sell a book that's alleging a generic far right conspiracy theory about "neo-marxism".

“One Marine told us that military history training session was replaced with mandatory training on police brutality, white privilege, and systemic racism.

The defense secretary being questioned did not deny these assertions. But the truly motivated will find ways to call this "not evidence" as well. Only 100% incontrovertible proof counts as evidence for assertions they don't like. The bar is, of course, much lower for things they'd like to believe.
