The friction came to a head in early 2017 when senior officials offered Trump charts and graphics laying out the numbers and showing a “hockey stick” spike in the national debt in the not-too-distant future. In response, Trump noted that the data suggested the debt would reach a critical mass only after his possible second term in office.

“Yeah, but I won’t be here,” the president bluntly said, according to a source who was in the room when Trump made this comment during discussions on the debt.

The episode illustrates the extent of the president’s ambivalence towards tackling an issue that has previously animated the Republican Party from the days of Ronald Reagan to the presidency of Barack Obama.

But for those who have worked with Trump, it was par for the course. Several people close to the president, both within and outside his administration, confirmed that the national debt has never bothered him in a truly meaningful way, despite his public lip service. “I never once heard him talk about the debt,” one former senior White House official attested.
