1)  Stump has become "annoyed" with Stump Jr's girlfriend.

 
2)  She has signed on to be a campaign aide for my former governor Eric Greitens, who's running for U.S. Senate in 2022.

 
3)  Greitens, a Con (of course), was forced to resign as Missouri's governor in 2018 over allegations of blackmail & sexual abuse.  A good, solid "family values" guy.  That's almost tame in comparison to insurrectionist Heil Hawley.

 
4)  Trumpolini is pissed because he believes Greitens will use Jr's girlfriend to sponge off her present ties with the Trumpolini name without getting his formal permission (or agreeing to pay him some name association royalties).  I can see Stump suing Greitens for infringing on his patented S.O.P.
