Little direct evidence has been made publically available on either set of allegations.  What we have for the most part are leaks and anonymous sources being reported in the media.  While the white house complains about the leaks, it decided to leak information to Nunes instead of presenting it to the investigating committees.  The president has the power to declassify the information on all of these matters, why does he not do so?  Hopefully the investigative committees will do their jobs and get to the bottom of these allegations wherever they may lead.
