Trump Transition Team Faces Spending Scrutiny by Official Watchdog

...

Warren and Cummings cited media reports that Trump's daughter, Ivanka Trump, attended a meeting with Japanese leader Shinzo Abe and that Trump spoke to at least one foreign leader on his personal cell phone during the transition. "There is no indication of whether this call or Mr. Trump's other phone calls with foreign leaders were on secure phone lines," the letter says.

Their letter also questioned whether taxpayers paid for Trump to travel on his personal plane during the transition. "There is no transparency with regard to transition expenditures, raising additional questions about how taxpayer funds may be flowing into Mr. Trump's pockets," it says.
