A New York tenants rights group and local politician said on Monday they would launch an investigation into the real estate company formerly headed by Jared Kushner, a top aide to President Donald Trump, over alleged falsification of building permits.

The group and the politician, a city councilman, said they had uncovered evidence that Kushner Companies, the developer headed by Kushner until early last year, had falsified more than 80 work permits involving 34 buildings in New York.

They made the allegations at a press conference in front of the 41-story tower on Fifth Avenue in Manhattan controlled by the Kushner Companies. The tower has been at the center of potential conflicts of interest involving Kushner, who is also Trump's son-in-law.
