People say such strange things in the MSM.
Trump cannot sack Mike Pence as vice-president (the vice-presidency is an elected position);
he does not control the Republican party (he’s probably not one of the richest 100 guys in New York City, and may not even have been in the top 10 during his heyday);
he has no political future (and he is at serious risk of going to prison – he’s no Andreotti or even a Mandelson).
