Is the wasteful spending that Elon and Trump/the White House keep referring to actually real?

I see Trump, Elon, and the WH press secretary referring to a lot of supposed wasteful spending by USAID and the government in general like:

• $50 million for condoms for Gaza
• $2 million for sex change operations in Guatemala
• $20 million for Sesame Street in Iraq

And various other things. What I don't see is anyone backing up these claims with factual information or any sort of proof that this money was actually earmarked for this stuff. If it is true, why weren't these kinds of expenditures brought to public attention before Trump came back?

While I'm sure the government wastes a lot of money generally, it's hard to tell what's true and what isn't with these people.
