Number one, how does he suggest we "rebuke" her - say 'bad girl, no-no, now promise not to do it again or we'll say 'bad girl, no-no' again'?
Number two, why not do both - make her into an example of how not to be a House Speaker, and prosecute her for violation of the Logan Act, among other things?
I got the ultimate display for Speaker Pelosi. If I were the US Attorney for DC, I would wait for her to come back to the US. Then I would wait until she is on the podium of the US House. Bring the FBI in and arrest her on the Speaker’s podium. Then bring her down in cuffs doing the ultimate perp walk down the stairs of the US Capitol.
