They should pull a LOIS LERNER!
Appear, make a statement, and invoke the 5th.
” This entire effort to destroy Donald Trump is a hate-filled witch hunt orchestrated by partisan, sore loser Democrats who STILL have not accepted the result of the 2016 election.
I will not take part in this farce. My suggestion is the Democrats get over their hatred and rage and try to find time to make a difference in the lives of all Americans. With that I invoke my constitutional right to invoke the my 5th Amendment privilege.”
PERFECT
That would be amazing.
