NBC News reported Thursday that Fiona Hill, a former special assistant to the president, will tell House lawmakers that Giuliani and Trump's ambassador to the European Union, Gordon Sondland, went around the NSC and official White House procedures to speak to the president about Ukraine.


Hill's attorney did not immediately return a request for comment from The Hill.

The White House has opted to use executive privilege to stop officials from testifying before Congress, but it remains legally unclear if the president can force former officials who are now private citizens from testifying.
