(CNN) Donald Trump Jr. told House investigators that he did not communicate directly with his father when confronted with news reports about his June 2016 Trump Tower meeting, according to multiple sources with knowledge of his testimony.

Instead, Trump Jr. said he was speaking to White House aide Hope Hicks about how to respond to the reports. He said President Donald Trump, according to the sources, was debating between a longer and a shorter statement while the President and Hicks were aboard Air Force One.
