WBUR’s “On Point” broadcast featuring former U.S. National Security Adviser Jake Sullivan was interrupted by two pro-Palestinian protestors on Sept. 16. While Sullivan was responding to a comment on the United States’ involvement in Israel, two pro-Palestinian protestors erupted in chants. Sullivan, who oversaw national security protocol under former President Joe Biden for four years, left his position eight months ago. Additionally, Sullivan addressed the lack of cohesion within U.S. institutions and resulting threats to national security. “I think what makes America great [is that] people have First Amendment rights and they’re allowed to speak out,” Sullivan said.
