U.S. lawmakers asked Credit Suisse to hand over information related to the bank's "compliance" with sanctions on Russia, the Wall Street Journal reported on Monday.

Credit Suisse reportedly instructed investors to destroy and erase information over a debt deal with Russian rich clients.

"This report raises significant concerns about Credit Suisse's compliance with the severe sanctions imposed by United States and its allies and partners," the U.S. committee chairs said in a letter to the bank.
