Why is it ok to have fraud for the PPP program but it's unacceptable for the current bill?

Just heard on MSNBC that the republican panel said if there is fraud for the current democratic bill, it will be bad and would destroy the credibility of the bill. They are the same people who praise the PPP program breathlessly. We saw there were frauds where people were charged by using the fund for a boat or a new car. Why is it ok for the PPP program to have fraud but suddenly when it's a democratic bill and it is unacceptable to have any fraud?

PS. I am not saying there will be fraud for the current bill.
