There is no question at all that Nasty Nancy's act of ripping up the SOTU speech is premeditated.
It is easy to see that she had the pages already separated into small groups that she could easily pick up.
In this video you can see she works from her left to her right, reaching down and smoothly picking up a group to rip up.
There is no fumbling or time spent separating pages.

I agree, Nasty planned this stunt from the very beginning.
It is not sitting well with America, even dims are saying that was too petty, beneath her office as Speaker.
I see a YUGE backfire.
