Joseph Biden actually said...

My sons have always been my rock. They've been there for me through thick and thin.

I'm so proud of my sons and the men they've become. They make me a better person every day.

I'm so blessed to have my sons in my life. They're my best friends and my biggest supporters.

My sons are the reason I fight for what's right. I want to leave the world a better place for them and for all future generations.
