Good question from the Trump War Room: “What’s he hiding?”

WATCH: Joe Biden explodes when a reporter asks a very simple question:

"How was your role as Vice President in charge of policy in Ukraine and your son's job in Ukraine, how is that not a conflict of interest?"

Biden: "I'm not going to respond to that!"
