What's the difference between encouraging someone and egging him on?

I'm trying to read "Scoop: How Trump's team egged him on during CNN town hall" by Mike Allen (Axios).

The "scoop" is this:

Backstage during the first commercial break, Axios has learned, Trump adviser Jason Miller — as if psyching up a boxer in his corner or egging on a bully — showed Trump moments-old tweets from Democrats blasting CNN and saying Trump was winning.

"Secrecy is exactly what is wrong about this."

Below, @axios on Trump Mar-A-Lago raid. Secrecy is exactly what is wrong about this. Secrecy allowed wild media speculation in Trump-Russia matter. As target, Trump is entitled to copy of warrant, underlying affidavit. He should make them public immediately. Today. pic.twitter.com/96FZ20lcZB

The image says: "The bottom line: These investigations are top secret. So more likely than not, we won't get the full picture any time soon."

That's from Mike Allen at Axios: "What we know — and don't know — about the Trump raid."
