On March 14, 2017, the first two pages of Trump's 2005 federal income tax returns were leaked to Rachel Maddow and shown on MSNBC. The document states that Trump had a gross adjusted income of $150 million and paid $38 million in federal taxes. The White House confirmed the authenticity of these documents and stated: "Despite this substantial income figure and tax paid, it is totally illegal to steal and publish tax returns."
Trump's victory was considered a stunning political upset by most observers, as polls had consistently showed Hillary Clinton with a nationwide—though diminishing—lead, as well as a favorable advantage in most of the competitive states. Trump's support had been modestly underestimated throughout his campaign, and many observers blamed errors in polls, partially attributed to pollsters overestimating Clinton's support among well-educated and nonwhite voters, while underestimating Trump's support among white working-class voters. Actually, the polls were relatively accurate, but media outlets and pundits alike showed overconfidence in a Clinton victory despite a large number of undecided voters and a favorable concentration of Trump's core constituencies in competitive states.
Trump is the wealthiest president in U.S. history, even after adjusting for inflation. He is also the first president without prior government or military service. Of the 43[nb 4] previous presidents, 38 had held prior elective office, two had not held elective office but had served in the Cabinet, and three had never held public office but had been commanding generals.
Trump's predecessors merged their campaign committees into their party's committee following their election victories. Following his 2016 election victory, Trump eschewed this presidential tradition and retained a separate campaign committee. Trump's campaign committee continued raising funds. In December 2016, the campaign raised $11 million. These moves indicated that Trump was already eying a 2020 run.
