I saw a video of some senate function where familiies were in attendance. Jeff Sessions was fixing the clothig of his granddaughter while standing next to Biden. Biden started to reach out to touch the kid and Session frowned then turned her away and moved her off. It was really obvious. He didn’t want the kid anywhere near Biden.
He does more than frowned. He actually swatted Biden's hand away. Look a bit before 3:00 in this video. Keep watching and they show it again in slow motion.
