Story from 3 yrs ago:
Obama administration spying.
This is the first time that Paul mentioned another senator is also concerned about the Obama administration's surveillance.
He said if this proves to be true, it's a much bigger story than any allegations about collusion between the Trump campaign and Russia.
"It's about your own government spying on the opposition party, that would be enormous if it's true."
