Pointing to money that was spent differently than you think it should be is not fraud, no matter how much you want to claim it.
Pointing to money being spent in suboptimal ways is not fraud. Maybe it's waste - but often it's what the law calls for (aka definitionally the opposite of fraud).
Yelling very loudly about how it's all fraud and waste is not proof. It doesn't matter how loudly you yell.
Repeating "there's so much fraud, omg, fraud everywhere, soooo much fraud" over and over is not proof. Even if your repetitions would make an animated gif jealous.
Actually prove the fraud: Show that the money was spent in a way different than proscribed by law, that the people authorizing the spending were lying, and there was direct enrichment of someone via those lies and misspending. It's not hard if of it around.
