The schedules, which cover almost every working day since the midterms, show that Trump has spent around 60% of his scheduled time over the past 3 months in unstructured "Executive Time".
The leaked schedule shows 60 percent of the president's time since last November's midterm elections set aside for him to casually meet with staff members, peruse the stack of newspapers delivered to his office, watch television and make phone calls to officials and informal advisers.
"While he spends much of his average day in scheduled meetings, events, and calls, there is time to allow for a more creative environment that has helped make him the most productive President in modern history".
Axios also spoke with top aides to those former presidents, who shared details about the way their bosses allocated time. But an analysis from The Washington Post cross-referencing the Axios schedule with Trump's Twitter data from Media Matters for America shows the president typically sends his morning fusillade of tweets before his workday actually begins.
"President Trump has a different leadership style than his predecessors and the results speak for themselves", Sanders said in the emailed statement, according to Axios.
What does Donald Trump do with his time?
'He's always calling people, talking to people, ' said one senior White House official. He would usually be in the Oval Office at 9 a.m. and would have six meetings plus intelligence briefings.
Alexi McCammond and Jonathan Swan commented: "The president sometimes has meetings during Executive Time that he doesn't want most West Wing staff to know about for fear of leaks..."
Axios published three months of the president's day-to-day private schedule on Sunday, citing an unnamed "White House source" as the person who supplied the 51 schedules.
"President Trump has ignited a booming economy with lower taxes and higher wages, established the U.S. as the No. 1 producer of oil and gas in the world, remade our judiciary, rebuilt our military and renegotiated better trade deals", Sanders added.
Huntsman also noted that the White House has a problem with leaks in general, plus there's no telling what Trump's really doing in his "executive time" since the term is still loosely defined.
White House officials dispute the characterization Trump is not interested in such topics or has only a superficial understanding of them.
"Executive time" does not necessarily preclude meetings, Axios said, since they may be organised on the spur of the moment and include calls with heads of state, political meetings and meetings with counsel in the White House residence.
