IMHO: The congressman was goaded. I Imagine that what we are now seeing as the IM has been doctored to exclude the goading of the page and maybe even spiced up a little. If the original is found and is different that what was released someone along the chain of possession is getting a can of whupass opened on them. That is not a prank, that is a felony.
That is true. I forgot about how somethings have appeared doctored. That would cross the line if that happened
