This actually makes sense. All three of these lawyers were representing people who were targeted by illicit CIA/FBI surveillance during the 2016 election campaign.
This is also very big news -- but not in the way the media reports suggest. There is no question that the involvement of U.S. and Ukrainian figures in the 2016 election is the focus of these efforts by private lawyers as well as (apparently) the U.S. Department of Justice.
And all three are/were private citizens....not government or Whitehouse staff.
