Trump escalated his attacks on Schiff last week, alleging in a July 15 Truth Social post that the Democrat had engaged in a “sustained pattern of possible mortgage fraud,” which the president claimed had been discovered by the Federal National Mortgage Association’s Financial Crimes Division, also known as Fannie Mae.

The president accused Schiff of falsely claiming a Maryland home as his principal address to qualify for a cheaper mortgage interest rate.

Schiff’s spokesman told the Los Angeles Times that the senator followed legal advice and was open about moving between two houses, one in his home state of California and the other near where he works in Washington, DC.

A Fannie Mae report acquired by the outlet did not accuse Schiff of mortgage fraud or any other crimes, but it did notice “a sustained pattern of possible occupancy misrepresentation” over which property he and his wife identified as their principal address on loan records.

The type of mortgage fraud case involving Schiff is typically straightforward and difficult to defend against, according to financial crimes experts, who warn the senator could face substantial fines and penalties.
