Gallup has conducted continuous confidence surveys of American presidents since the 1930s. Incumbent President Donald Trump's confidence figures for December were among the lowest the company has ever measured, the newspaper reports.
Gallup's decision comes a few weeks after Trump threatened opinion poll companies.
“Fake and fraudulent opinion polls should in practice be a crime,” he wrote on Truth Social.
Gallup denies that the decision to stop conducting confidence surveys has anything to do with Trump's statements, and says the decision applies to all politicians at the individual level.
