Intel Chair (Chair of the Senate Intelligence Commit) this morning on CNN State of Union, when asked whether Malaysia has cooperated with the US intelligence with sharing of information, responded that Malaysia is in charge or this, US can not demand information from them. She states further her group does not know more than what the media knows.
What does this tell you? It tells me that US intelligence denies real cooperation with the Malaysia and Malaysia has information that we do not know. This clearly suggests that Malaysia is hiding things or lying.
