Corker, who is the third-ranking Republican on the Senate Banking Committee, did not properly disclose at least $2 million in income from investments in three separate hedge funds in Tennessee, as well as millions of dollars in income from commercial real estate investments because of an accounting error, and millions of dollars in various other assets and income from transactions.

According to the report, Corker filed amendments to his previous personal financial reports on Friday.

“After completing a full, third-party review, we have corrected this oversight,” Corker said in his statement to the newspaper, adding that he had hired an accounting firm after the Journal began making inquiries.
