NBC News reports:
U.S. officials told NBC News on Thursday that they have been concerned for months that President Donald Trump has been discussing sensitive information on an unsecured cellphone with informal advisers, including Sean Hannity of Fox News.
The information comes after The New York Times reported that Chinese and Russian spies have been listening to personal phone calls Trump has made from his cellphones. Several aides to Trump have repeatedly warned the president of the routine eavesdropping on his unsecure phones, The Times reported.
Trump, however, has refused to give up his iPhones, the paper said. Critics have noted that Trump’s own tweets identify themselves as being posted to the micro-blogging site via Twitter’s official iPhone app.
