CNN analyst and national security expert Juliette Kayyem called in to Boston Public Radio on Wednesday, where she recapped a Wednesday report from ABC News accusing officials from the Department of Homeland Security of withholding information about Russian interference in the upcoming election.

The report, she noted, also details how attacks on Joe Biden from President Trump appear to “either amplify, mirror, or follow” messaging from Russian bots across social media.

Kayyem also weighed in on a new ad from Joe Biden's campaign, and explained why the president is losing a “culture war” over face masks.

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