Birtherism. Trump began insisting in 2011 that Barack Obama may not have been born in the United States. He once said a "very credible source" had informed him that Obama's birth certificate was fraudulent and claimed to have sent investigators to Hawaii to research the matter. Trump has also suggested Obama may be a Muslim who is sympathetic to the goals of groups like ISIS. (Obama is an American-born Christian.)

Steve Bannon. The former chairman of Breitbart News helped run Trump's campaign and is a senior White House adviser. Bannon once proudly described Breitbart as "the platform for the alt-right," and under his leadership the site published an infamous article which celebrated the work of several white supremacists, including Richard Spencer, who was one of the leaders of the Charlottesville rally and who made headlines for using Nazi slogans and gestures at a Washington, D.C. celebration of Trump's inauguration. (Breitbart also famously posted some of its stories under the heading "Black Crime.") Bannon has repeatedly and publicly endorsed The Camp of the Saints, a novel popular in white-pride circles in which black Americans, "dirty Arabs," and feces-eating Hindu rapists (among others) destroy civilization. The book refers to black individuals as "n[******]s" and "rats." Bannon has also reportedly praised a far-right French writer named Charles Maurras who was sentenced to life in prison after World War II for collaboration with Nazi occupiers. And he's complained publicly that too many tech CEOs are Asian American. And he reportedly told his ex-wife that he didn't want their children attending schools with significant Jewish enrollment.

Milo Yiannopoulos. The Nazi-fetishizing former Breitbart staffer who co-wrote the white-supremacist article described above can thank Bannon, who has called his work "valuable," for launching his career. Trump's first national security adviser, Michael Flynn, called Yiannopoulos "brave" and said he was a "phenomenal individual" in November 2016. In February of this year, Trump himself tweeted a threat to revoke the University of California at Berkeley's federal funding because it canceled Yiannopoulos' appearance on campus. Yiannopoulos subsequently resigned from Breitbart during a furor over approving remarks he made in 2016 about pedophilia--but it appears that his career is still being funded by Robert Mercer, a right-wing billionaire whose daughter Rebekah served on Trump's transition team.

Alex Jones. Jones' site InfoWars advocates paranoid beliefs of all sorts, including but not limited to alt-right-adjacent theories about the "Jewish mafia" and "globalists," such as the Rothschilds, who manipulate world events to enrich themselves. Trump called Jones "amazing" during a 2015 interview, and the White House seemingly confirmed to the New York Times that Trump and Jones occasionally speak on the phone.

Sebastian Gorka. Ostensibly a counterterrorism adviser, Gorka's job appears to consist entirely of making grandiose and factually erroneous declarations during Fox News appearances, and he is reportedly a member of a far-right Hungarian group called Vitézi Rend that collaborated with the Nazis during WWII. (He denies it.)

Julie Kirchner. Previously the executive director of the Federation for American Immigration Reform, Kirchner was appointed to work at the federal Office of Citizenship and Immigration Services by the Trump administration in May. The Federation for American Immigration Reform's founder and its current president are both interested in eugenics and crank race science; both have complained that immigration undermines whites' dominance.
