Biden condemned the violence in Kenosha after three nights of unrest sparked by the police shooting of 29-year-old Jacob Blake.
“It is needless violence,” Biden said in a video posted on Twitter. “Violence that endangers lives and guts businesses and shutters businesses that serve the community. That's wrong.”
The former vice president went on to say that America needs to unite, heal, do justice, and end violence and systemic racism.
"They’re [Democrats] going to point to it, again and again, saying he’s denounced this violence," Baier said. "But, he did not do it at the DNC, at the convention."
The Fox News chief political anchor added that Democrats' silence on the issue "gave Republicans an opening … and this week they took it.
"You’ve heard this again and again and again about Democrats not speaking out on violence," he went on. "Now, the question is, where does this go?
"I’ve heard Democrats blaming the Trump campaign and the Trump Administration for the chaos … [but] that doesn’t seem to fly."
