Rachel Maddow outlines the visit last week by the head of three spy agencies to US soil... including one of them that is barred from US soil due to sanctions. It's a pretty cool clip that is outlined very well and sourced.
If you couple the visit of the head of the three russian spy agency with the release of the memo to obfuscate the meeting, you basically get russian spies walking and mingling in the open with trump admin officials with very very tiny coverage. It's classic.
