I’m not sure what’s Masonic about the handshake. It looked normal to me, but I don’t know that much about such things.
BTW, there are still some who believe Pence is a white hat and is playing a role at Trump’s behest. That would make him a triple agent I guess. Just throwing it out there.
An argument in favor of this theory is the fact that Pence is reportedly opposing the current attempts to remove Trump via the 25th amendment. Of course he could still be a black hat and oppose using the 25th amendment. After all, optics matter and vindictiveness is not part of Pence’s public persona. This could just be Pence attempting to bolster his fair minded, sober, and judicious image.
