Former Vice President Joe Biden said he asked Kamala Harris to always tell him the truth and "to be the last voice in the room."
Here's what Biden said:
"When I agreed to serve as President Obama's running mate, he asked me a number of questions most important, he said to me, he asked me what I wanted most ... I told him I wanted to be the last person in the room before he made important decisions. That's what I asked Kamala. I asked Kamala to be the last voice in the room."
