The judge reminded jurors how they should decide so as to send Trump a message is the translation.
So they cannot bring up the shooters past convictions or his deportations, but it is ok for the judge to repeatedly bring up Trumps comments on the shooting. I am not a lawyer, but that surely seems odd to me.

Because reminding SF jurors that Trump would like a conviction was such a good idea!
