This is what has been reported, and Trump didn't dispute it when asked by the press.

As for "standard procedure" and counter-intelligence, who knows? I'm not a member of the intelligence community. Are you?

The point of my comment is that, to many laypeople, Trump's inaction doesn't look good and that creates an optics issue for him. "Why would he let a Chinese spy who was potentially trying to use Huang to influence the president's US-China policy stay close to him?"

Given how the administration operates, you can expect Trump's lackeys to spin the truth (if not lie) to make his actions look more favorable to the public.
