According to the report, these government officials faked their identities to cover up. This is a case of corruption and gambling addiction. Funds that would have been used to take care of the people have been misused by corrupt officials to fuel their addictions.
I think it's more a case of psychopathy or sociopathy. Many psychopaths end up in politics; they have an inflated ego and know how to manipulate people in order to climb the ladder. The fact that they are corrupt is already a clue. But on top of that, spending all that money at the casino indicates a personality that just wants more and more, more power and more money.
