If there are people I can trust in my life my sister is at the top of the list. But, that is not how it was between Fidel Castro and his sister.
A sister of Cuba's former long-time leader, Fidel Castro, has admitted spying for the CIA in the 1960s.
She couldn't stand watch the killings and torture that her brother was committing at the time, and so, she decided to betray him.
Juanita Castro, who now lives in Miami, said she had gathered sensitive information for the US for three years.
In her memoirs, she said she had fallen out with Fidel and her other brother Raul - Cuba's current president - over the killing of their opponents.
She participated in helping dissident escape the island. So far there was no reaction from US or Cuban authorities whether this story is true or false.
Ms Castro, 76, said she had helped to warn and hide Cuban dissidents before finally fleeing the island in 1964.
There has been no immediate reaction from the US or Cuban governments.
I've seen so many revolutions turning out this way. Especially in Africa. When the populists stage a revolution, only to win and the leader just end up consolidating power and imposing dictatorship.
She agreed to help because she had become disenchanted when Fidel abandoned the nationalist democratic revolution he promised and instead imposed a one-party Marxist state "simply out of the need to hold power", she said.
"He betrayed the thousands of us who suffered and fought for the revolution that he had offered, one that was generous and just and would bring peace and democracy to Cuba, and which, as he himself had promised, would be as 'Cuban as palm trees'," she wrote.
I wonder what Raul is going to say about this. What does Fidel have to say, himself? But, just I wish Liz Cheney would learn from this woman, and reject her father's crimes.
