@Jorsh because that's not how reality works?

Keep in mind that the appointment to judge required approvals of many people. Do you think she's mandated to do them all favors? No of course not.

The way the US system is set up, once such a judge is appointed they don't owe anybody anything. There are specific rules in place to prevent that.

Heck, if the judge were to act inappropriately and do Trump a favor she stands to lose her job.
