President Donald Trump is reportedly telling foreign leaders to call him directly on his cellphone and giving them his phone number, prompting security and transparency concerns. Current and former U.S. officials told the Associated Press that Trump specifically told Canadian Prime Minister Justin Trudeau and Mexican President Enrique Peña Nieto to call him directly. Trudeau has reportedly taken Trump up on the offer. Additionally, a French official said Trump and French President Emmanuel Macron exchanged phone numbers. World leaders typically communicate on secure phone lines, as opposed to government-issued or personal cellphones. Trump met with Macron, Trudeau, and others at the G-7 Summit in Italy last weekend.
