This is presumably a rebuke of his campaign chairman Paul Manafort, who has been trying to get Trump to restrain himself and to act more presidential. Shannon, on the other hand, has been urging him to be his true outrageous self, which won him the Republican nomination.
Manafort, however, will remain at his post. Meanwhile, new information is coming out about his connection to Russian authoritarians and their operatives.
Conservative columnist Rich Lowry says that it’s as if Republicans have switched sides in the cold war!
UPDATE: Manafort quits as campaign chairman.
