Beau, my dear friend, who we remember here today

Question

Does "my dear friend" refer back to "Beau"?

It’s his love for Jill, who will be an incredible first lady.

It’s his love for Hunter, Ashley, his grandchildren, and the entire Biden family.

And while I first knew Joe as Vice President, I really got to know him as the father who loved Beau, my dear friend, who we remember here today.

To my husband Doug, our children Cole and Ella, my sister Maya, and our whole family — I love you all more than I can express.
