Word to the wise in the chump-world hotseat.
Use a medical reason. Y'all had strokes or heart attacks and cannot possibly show up to testify UNDER OATH.
Just like the never-ending IRS audit gambit/ruse/LIE of the steadfast jacka** none of these folks will ever recover sufficiently to show up to Congress for their testimony.
Y'all are welcome. Use the ruse free of charge. It could work real good for ya.
