After Tom Carper voted no on confirming the Republican racist Attorney General, Carper rushed up the aisle to hug him. This is not normal. This is what Lizard People do. The only explanation then is that Tom Carper is a lizard person.
From The Hill:
A handful of Democratic senators — including Manchin, Sen. Joe Donnelly (Ind.) and Bob Menendez (N.J.) — went over and shook Sessions’s hand after the vote. Sen. Tom Carper (D-Del.), who didn’t support Sessions, hugged him on the Senate floor.
Here’s the video from C-SPAN. I believe that this is Carper we see rushing up the aisle in the bottom right of the screen to embrace the Republican attorney general in what can only be described as some sort of reptilian courtship ritual.
