There is much more to come about the surveillance of Trump and his associates, which reportedly started after November’s election.  Warrants required for the investigation had to be requested by someone high up in the Obama administration and there had to be probable cause that something nefarious was occurring.  Who requested them and what was the probable cause?  Since the President-elect and his associates were involved, it was highly possible that a Constitutional crisis might result.  Therefore, it seems to me that the President of the United States would have been briefed on the planned investigation or during its conduct.  What did he know and when did he know it?  The Congressional investigation needs to continue until these questions are answered.  Americans have a right to know.
