Surveillance on Americans began in 1993 when the Clinton White House had FBI files on hundreds of Republicans, many no longer working for gov’t or holding elected office.
This continued when Obama was elected using electronic means.
We know that Obama was routinely spying on journalists and congress members. The Senate computers were surveilled before passage of Obamacare.
The IRS was weaponized to block groups from forming 401c(3) organizations opposed to Obama’s re-election. Treasury was involved in exposing financial records of Americans.
Maybe its finally dawning on these Senators that they were spied on too.
They didn’t care much when it was Trump or Tea party members but in their mind they were off limits.
Until they weren’t.
