"Make good" and "federal bench"

Question

Reading this article, there is a line,

President Joe Biden signed an executive order on Friday empaneling a commission to examine possible reforms to the Supreme Court and federal judiciary, making good on a campaign trail promise sparked by his predecessor's tilting of the federal bench

Question 1

What does "make good" mean from the following definitions?

1. If you make good some damage, a loss, or a debt, you try to repair the damage, replace what has been lost, or repay the debt.

2. If someone makes good a threat or promise or makes good on it, they do what they have threatened or promised to do.

3. If someone makes good, they become successful, famous, or rich.

I guess without any support here make good would mean by 2?

Question 2

What does federal bench mean here?

Would that mean possibly the line of judges changed by the former president Trump here?
