A Brooklyn construction magnate was sentenced Friday to a year of probation for working with a Turkish government official to funnel illegal campaign contributions to New York City Mayor Eric Adams, resolving one of two related federal cases after the mayor’s criminal charges were dropped. Erden Arkan, 76, told Manhattan federal Judge Dale Ho that he regretted his “poor judgments” in engaging in the straw donor scheme, which helped Adams fraudulently obtain public money for his 2021 mayoral bid under the city’s matching funds program. Ho cited Arkan’s age and otherwise clean record in imposing the sentence, telling the Turkish-born businessman that his immigrant success story “exemplifies the American dream.”
