Washington (CNN) President Donald Trump has continued to use his personal cell phone to make calls, despite repeated warnings from his staff that the practice could leave him vulnerable to foreign surveillance, multiple officials told CNN. The Democratic impeachment inquiry has resurrected concerns about the security and potential vulnerability of the President's communications. Witness testimony revealed some top officials repeatedly failed to follow protocol intended to prevent sensitive phone conversations, including those involving the President, from being intercepted by foreign intelligence services. Normally, a US ambassador talking to the President would do so from the embassy using a secure line, one former intelligence official told CNN. Cell phones, the former official said, were much more vulnerable than calls made at secure communications facilities.
