If they bring up Russia-election-meddling again in this trial the Trump team should demand Christopher Steele as a witness. And Horowitz to reiterate his finding that the “Steele Dossier” was bogus and the FBI agents who knew it was bogus and ... so on and so forth.
Maybe Steel should be brought up, but he’s a UK citizen, and the subpoena has zero power over him.
Some people suggest that even Joe Biden might have the power to avoid a subpoena to appear. Hunter Biden...I would speculate...will be leaving for a foreign country in the next week and probably try to avoid the subpoena via that method.
