extemporaneously

The vice president has the facility to speak candidly and extemporaneously.

She spoke extemporaneously and at length, in one interview after another, about a tremendously fraught political issue that had long felt personal to Black Americans but was nonetheless novel — if not threatening — to mainstream America.

The chief must be comfortable speaking extemporaneously — and often in front of cameras — about the work of the police department through the progressive lens of the city’s elected leaders, including the mayor and City Council.

Well, she hasn’t spoken extemporaneously in public for more than about two total minutes since Biden passed her the torch three weeks ago, and we don’t know much about how she would lead the most powerful country in the world beyond the generalities of her stump speech.

Even though Biden’s campaign can’t love the idea of him appearing extemporaneously for a couple of hours, they need something to shake up the campaign.
