Does consideration of legacy in admission affect whether and how much you may donate to a college? (poll)

Our son may have been legacy-admitted and was asked to write a letter. He had just finished his Eagle project and he said he didn’t want another task added to his busy schedule. He had already gotten into Caltech and automatically to UCLA. So we don’t know if it was because of legacy that they asked for a letter.

Can you explain this a bit more? What does it mean to “write a letter.” About/for what?
