It began just as they appeared before the audience.
Vice President Kamala Harris walked across the stage into former President Donald Trump’s space, reached out her hand and introduced herself.
Trump, visibly taken aback, shook her hand.
The assertive move by Harris was one that ended up setting the tone for the next 90 minutes, where Harris made her case to become the nation’s next president as much through body language as she did through words.
And in that period, she repeatedly got under Trump’s skin, sending him into angry screeds where he struggled to stay on topic and, at times, careened into confounding anecdotes.
