It’s up to Greg Palast to provide some evidence for his claims. It’s not up to Barack Obama to file a lawsuit against a vague, weird conspiracy theory about why he ran for President to prove Palast wrong; I’m not even sure what damages he could sue for.
Hold on… now, I’m not even sure what the problem is :o
As far as evidence, he’s got memos that are authenticated. Not much to discuss there.
I’m thinking, you are probably objecting to his interpretation of the facts, right?
