Homeland security expert Juliette Kayyem spoke with Boston Public Radio on Wednesday about the current state of the 2020 presidential election.

“My biggest fear was a systemic breakdown of voting, such that you would get a real question from both sides that these counts were not legitimate,” she said. “There are huge issues around the post office, and we still have votes to count, but you didn’t see the kind of the thing I would’ve worried about.”

One potential threat, currently undetected, was nefarious interference from foreign governments, Kayyem noted.

“You didn’t see any activity in particular of foreign activity or disruption,” she said. “My worry was that that would lead to a majority of the population going to the streets demanding our democracy work better.”

Kayyem is an analyst for CNN, former assistant secretary at the Department of Homeland Security and faculty chair of the homeland security program at Harvard University’s Kennedy School of Government.
