Boston Mayor Michelle Wu proposed a $4.8 billion city budget that she says may need to be adjusted down the line depending on the outcome of potential federal funding cuts, some of which the city is already challenging in court.

The proposed budget marks a 4.4% increase from last year. It would eliminate nearly 500 city government positions that have been vacant for over a year.

Boston Mayor Michelle Wu kicked off her reelection campaign Saturday with a passionate call for “big progress on the big challenges."
