As head of the City Council's Redistricting Committee, Breadon was involved in the controversial redistricting of the City Council districts that occurred after the 2020 United States Census.[8] She sponsored the original "Unity Map" that arose from the redistricting process and passed the city council despite opposition from four white politically moderate Irish American members of the City Council, including Council President Ed Flynn, whose district was one of two that were at the center of the controversy surrounding the map.The map's controversy surrounded changes district 6 and district 7's boundaries. The map was passed into law in November 2022 after being signed by Mayor Michelle Wu.[9][10] However, the map was ultimately prohibited by preliminary injunction from being used in the 2023 Boston City Council election after a ruling by Federal Judge Patti Saris.[11] After the judicial ruling, City Council President Flynn tasked Councilor Ruthzee Louijeune, head of the Boston City Council's Civil Rights Committee, to oversee the process of drawing a map to be used in the 2023 Boston City Council election instead of Breadon. The resulting map was adopted by the council in a 10–2 vote[12] and signed into law by Mayor Wu.[13]
In June 2023, Breadon was the only white member of the City Council to vote in support of a budget that the City Council approved 7–5. The six other votes in support came from councilors who are persons of color, and all of the votes against the budget came from the remaining white city councilors.[14] Mayor Wu thereafter vetoed a number of amendments included in the budget.[15]
