The revelations threatened to put the controversy over Trump’s refusal to follow recent precedent and release his tax returns at the center of the presidential campaign less than 40 days before the election, after a week in which the Republican nominee has struggled to bounce back from a debate in which most analysts and scientifically conducted polls scored Clinton as the winner.

His campaign vehemently pushed back on the Clinton campaign’s effort to turn the report into an “October surprise” moment, saying Trump has a “fiduciary responsibility” as a businessman to pay no more tax than legally required. It also charged that the report proved that the Times and the “establishment media” are merely an arm of the Clinton campaign.

The report contains the first detailed tax documents about Trump’s financial empire that have been publicly reported. It was immediately picked up by Clinton’s campaign, which has sought to make Trump’s refusal to release his tax returns a major issue of the campaign.

Calling it a “bombshell report,” the Clinton campaign said the Times’ article “reveals the colossal nature of Donald Trump’s past business failures and just how long he may have avoided paying any federal income taxes whatsoever.”
