Zephyr Teachout, an unofficial Bernie's surrogate, wrote an article for The Guardian calling Biden corrupt.
What did our spineless hero do about it?
He apologized.
Lucky for him, Joe Biden accepted the apology and their friendship continues.
Watching those that support the old spineless fool trying to explain why he did it and trying to justify him in doing so is amusing. The Cult Of Bernie is still avoiding to see the truth - he's a controlled opposition and the only betterment he seeks is his own.
When he loses, again, he'll write another book. Make sure to buy it Bernie Bros.
