President Donald Trump has spent about 60 percent of his officially scheduled time over the last three months in unstructured "Executive Time," Axios reported Sunday, citing schedules leaked by a White House source.

An early riser, Trump typically spends the first five hours of his day in executive time, according to Axios. Although the private schedules list him as being in the Oval Office from 8 to 11 a.m. each day, he actually spends those hours in his residence watching TV, reading newspapers, and responding to what he sees in the news by phoning aides, members of Congress, friends, administration officials, and other advisers, the news site reported, citing six sources with direct knowledge of the matter.

"He's always calling people, talking to people," a senior White House official told Axios. "He's always up to something; it's just not what you would consider typical structure."

The news site reported that former White House chief of staff John Kelly introduced executive time into Trump's day because the president disliked being locked into a regular schedule.
