CNN's Wolf Blitzer discussed former President Barack Obama's DNC speech and his critique of President Donald Trump.
BLITZER: The former president of the United States, Barack Obama, delivering a scathing, a scathing attack against the current president of the United States, President Trump. This was a moment that we anticipated, that this would unfold, but not to the degree that it has unfolded. I've been watching President Obama, for example, since 2004 deliver speeches. This may have been the most powerful address he ever gave, a presidential address to the nation, not only strongly supporting the democratic presidential nominee, Joe Biden, right now, but going after the sitting president of the United States, and Jake, you don't see that very often. I've studied american history a long time, I don't remember a time when the immediate past president was going after the sitting president the way he did.
