The problem still is that Rama had to follow protocol before finally suspending her. And unluckily for him, he suspended her with a scandal hanging over his head (time wasn't on his side).
Regardless if he suspended her around the time of the Dollar Heist or long before, someone would've complained/been suspicious, and someone would've accused Rama of having an agenda.
The PP would've been suspended regardless, scandal or not.
P.S It's also possible that RET caught wind of the PP's suspension to be imminent, hence the leak and ensuing scandal.
