Nina Kouprianova, who also writes under the name Nina Byzantina, publishes articles lionizing Vladimir Putin, criticizing western media and appears on the Kremlin-funded RT network to promote anti-Ukraine talking points.
Spencer, the head of the innocuously named National Policy Institute, has also appeared on anti-American segments broadcast by RT, although the English-language network does not highlight his relationship to Kouprianova.
However, a profile posted on the Neo-Nazi Wermod & Wermod Publishing Group’s website shows the couple dining together with British psychology professor Richard Lynn, whose writings attempt to link ethnicity and race to intelligence.
The couple, who have a young daughter together, are currently separated, according to a recent Washington Post profile, which identifies Byzantina by her married name and does not detail her work.
“What I’m doing is hard,” he told the newspaper. “It can have a toll on a relationship.”
Kouprianova has also translated the work of Russian political scientist Aleksandr Dugin, who has been linked to nationalist and fascist groups in his home country, although she attacks Ukraine's leadership as fascist in her writings and television appearances.
Spencer, who took over as president of the white nationalist organization founded by conservative publisher William Regnery II, is credited with popularizing the term "alt-right" -- a catch-all phrase describing white nationalists, neo-Nazis and other bigots who congregate at Breitbart News.
A recent viral video showed Spencer greeting Trump's election win by shouting "hail victory" which translates in German to "sieg heil" -- and drawing Nazi salutes from a crowd gathered in Washington, D.C.
He's attempting to insert his beliefs and his organization into the political mainstream after the election of Donald Trump, although his stylish appearance is often described in more detail than his regressive views and international associations.
"He wore a fitted gray suit and smelled of Cologne Russe, his preferred scent because it mimics a version once made for the Russian royal family," wrote John Woodrow Cox in his recent Washington Post profile.
Spencer is more interested in Russian affairs than what its royal family once smelled like.
"I think that Putin and Trump in a way offer an alternative to what’s going on at the moment," Spencer said last year on RT. "They offer an alternative what you call neo-conservative or neoliberal foreign policy."
