Interestingly, Depape was a member of the green party:
DAVID DEPAPE WAS A MEMBER OF THE FAR-LEFT SAN FRANCISCO GREEN PARTY
Who is David DePape, Paul Pelosi's alleged attacker?
What we know so far about the man who attacked Nancy Pelosi’s husband
We'll know more tomorrow, and a lot more in a week.
I gotta say, though, It is rather dificult to survive a "severe" hammer attack to the head at any age. A man his age surviving at all is amazing. Must've been love taps.
