The claims of fraud are a pretext for going into the agencies and making the partisan changes they wanted to make anyway. There's no point asking for a detailed discussion because the whole plan is to use the discussion of fraud as cover for the thing they're actually doing.

I think wired nailed it:

"This is incompetence born of self-confidence. It’s a familiar Silicon Valley mindset, the reason startups are forever reinventing a bus, or a bodega, or mail. It’s the implacable certainty that if you’re smart at one thing you must be smart at all of the things."

"And if you don’t believe in the public good? You sprint through the ruination. You metastasize from agency to agency, leveling the maximum allowable destruction under the law. DOGE’s costly, embarrassing mistakes are a byproduct of reckless nihilism; if artificial intelligence can sell you a pizza, of course it can future-proof the General Services Administration.
