Now, one tweet shows just how deep their bromance has gotten.
For President Obama's 55th birthday, Biden tweeted a picture of a friendship bracelet that POTUS made for him at some point the past.
The handmade accessory is a touching tribute to their friendship:
Happy 55th, Barack! A brother to me, a best friend forever. pic.twitter.com/uNsxouTKOO— Vice President Biden (@VP) August 4, 2016
The two have often shared stories about their strong bond.
Biden told Charlie Rose just how close the two were when he joined CBS This Morning to say that Obama was one of the few people Biden could confide in while his son, Beau, was dying of cancer. "He was there for my son. He was the only one, when my son was dying, that I was able to be completely candid with," he said. "He was genuinely moved... So it's a genuine friend — I respect him."
Obama has returned the sentiment in the past as well, like at the 2016 Correspondents' Dinner, when he said, "I tease Joe sometimes, but he has been at my side for seven years, I love that man. He’s not just a great vice president, he is a great friend."
Their bond is clearly strong, perhaps as strong as their new friendship bracelets.
While both men will be out of the White House come Obama's 56th, we can be sure that this is the first of many adorable birthday presents in the future as their relationship will clearly continue well into the future.
