It was an angry Joe Biden who came out on the offensive today in Iowa against Donald Trump. He accused Trump of “using every element of his presidency to try and smear me.”

But that was just the beginning. According to Politico, Biden went on to say:

“You should be asking him the question: why is he on the phone with a foreign leader, trying to intimidate a foreign leader?” Biden said. “This appears to be an overwhelming abuse of power. To get on the phone with a foreign leader who is looking for help from the United States and ask about me and imply things … this is outrageous. You have never seen anything like this from any president.”
