' I agree with WW that they are trying to protect Obama, and they obviously couldn't keep a lid on it for much longer.'
Not sure. There is the whole thing about Obama emailing Hillary at her private email address etc and him having a disguised address, but if it is all reinvestigated then that might all come up again.
Roger Stone, one of Trump's friends, said that a decision like that would have had to go right to the top, to Obama, because Comey and Loretta Lynch etc all report to Obama. He said it may be Obama sticking the knife into Hillary right near the end as there is lots of talk that Obama can't stand the Clintons.
