A San Francisco city council member who suggested that the Blue Angels should be banned from the city’s airspace expressed his frustration Sunday about outside criticism of the city and its policies.

It’s really strange." FILE: The Transamerica Pyramid and Sales Force tower are seen at sunset in San Francisco, Calif., on Monday, Jan. 17, 2022.
