FOX NEWS -- Sen. Adam Schiff, D-Calif., is under criminal investigation for mortgage fraud, a Trump administration source told Fox News.

Fox News host Laura Ingraham broke the news on Tuesday night on "The Ingraham Angle," saying the source said a criminal investigation is being conducted by the U.S. Attorney’s Office in Maryland on possible charges involving mortgage fraud.

The investigation comes a month after a story broke about the Federal Housing Finance Agency (FHFA) sending a criminal referral to the Department of Justice (DOJ) alleging that Schiff, in multiple instances, falsified bank documents and property records to acquire more favorable loan terms.
