A U.S. congressman who has read the Obama administration’s classified version of intelligence on the alleged Syrian poison gas attack says the report is only 12 pages – just three times longer than the sketchy unclassified public version – and is supported by no additional hard evidence.

Rep. Alan Grayson, D-Florida, a member of the House Foreign Affairs Committee, also said the House Intelligence Committee had to make a formal request to the administration for “the underlying intelligence reports” and he is unaware if those details have been forthcoming, suggesting that the classified report – like the unclassified version – is more a set of assertions than a presentation of evidence.
