Dems jumped out first because their political survival hinges on making certain that the Democrat Party, Barack Hussein Obama, Hillary Clinton, etc. are not connected to spying on Trump and company. Truth is they were in it up to their traitor necks. Democrat Party dying by its own hand.
And yet the more they deny it, the more people become aware.
“...did not offer evidence...” is a totally different event activity. To “offer” means the source was soliciting the audience and the Dems say that was not done. What was probably done instead was a data dump whether they asked for it or not, was offered or not.
Word slime of lawyers.
Now if the wording was “did not present evidence” then it’s significant.
