It would appear far worse than even that! Assuming Eric Ciaramella is the leaker who filed a false whistleblower report; he heard secondhand from Vindman about the call; he approached his bro working on Schiff's staff, they concocted the story after getting the IC IG to change the submission form to allow hearday information; leading to where we are today. One key finding will be who ordered the form change to allow hearsay. You are spot on that none of the people Schiff orchestrated to testify have any facts on their side.
POTUS should have asked for the resignation of every single Obama appointee on Day 1; he should rectify that now and replace them all with TD members! ;)
But those guys all identified as women, trans, persons of color, unicorns, climate changers, blah, blah,blah #provemewrong. ;)
