Anderson Cooper reacts with incredulity to Biden's claim

While both lies were glaring, the second one was ridiculous -- so much so that even CNN host Anderson Cooper, an openly gay man who aligns strongly with Democrats, found it laughable.

"Does it make any sense that Biden would ask President Obama not to endorse him?" he asked in incredulity Thursday evening on "Anderson Cooper 360." "Frankly I understand why President Obama would not want to endorse anybody at this stage but it does seem hard to fathom."
