Calla Walsh, described by one outlet as a former political staffer who became known at a young age, is the subject of reports about her later activities while in Tehran. The article says Walsh, now 21, rose to attention in 2020 when she was 16, for work connected to the reelection campaign of U.S. Senator Ed Markey in Massachusetts. The same coverage claims that, at a later point, Walsh is seen in Tehran chanting “Death to America.”

The reporting presented focuses on her earlier rise in U.S. politics and contrasts it with a later appearance in Iran. Details about the circumstances of the Tehran incident—such as timing, location, her role at the time, and the source or context of the chant—are not fully elaborated in the provided material. Across the available text from the outlet, the common elements are Walsh’s age, her association with Markey’s campaign during 2020, and the claim that she chants the stated slogan in Tehran.
