Donald Trump fraudulently inflated his net worth by as much as $2.2 billion per year, New York officials said in court filings unsealed Wednesday ahead of his upcoming civil fraud trial.

The new estimates came in filings from the New York state attorney general’s office, which is suing Trump, some of his adult children and his business empire for falsifying his net worth in an effort to obtain favorable terms from banks and insurance companies. The trial is set to begin Oct. 2.
