Did Edward Aubrey Clark organize the assassination?

[John Simkin]

Barr McClellan claims in his book, Blood, Money & Power: How LBJ Killed JFK, that Edward Aubrey Clark, was the key figure in the assassination of JFK. As Nigel Turner has pointed out: "His (McClellan) arch villain is Texan attorney Edward A Clark. He controlled LBJ's financial, legal and political fortunes for three decades from offices in downtown Austin. He accuses Clark, now deceased, of being the man who personally orchestrated the assassination of JFK when Johnson faced political ruin and possible imprisonment due to past misdeeds."

Has any other researcher found any evidence to support this claim?
