I have seen the video and heard the arguments for and against. In my opinion, the representative is unjustly accused. He did not let that fart rip.
I base my opinion on the fact that he is a democrat. I don’t believe any democrat possesses the necessary sphincter tension to produce a loud raucous fart. Bending over and catching the hard one in an effort to please one and all takes its toll.
It’s kinda like playing a trumpet. Without the pucker you are just pushing around hot air.
