Hillary Clinton is set to deliver a blistering speech about Donald Trump's "divisive 'alt-right' candidacy" in Reno, Nev., on Thursday.

"This alt-right brand is embracing extremism and presenting a divisive and dystopian view of America which should concern all Americans, regardless of party," the Clinton campaign said in a statement. "In her remarks, Clinton will contrast Donald Trump's divisive views and dangerous temperament with her vision of America that is stronger together and where everyone has a role to play in the future."

The "alt-right," or alternative right, is a group that opposes progressive causes and values while advancing the populist and nationalistic dogma that helped Trump rise within the GOP. The alt-right includes neo-Nazis and anti-Semites who have gained a large following online and on talk radio in recent years, stoked by media such as Breitbart News.

Clinton's speech about the "alt-right" in the Western battleground state comes after the Trump campaign hired Steve Bannon, former Breitbart executive, to be its CEO. Bannon has many fans among the alt-right and has vehemently opposed conservatives and Republicans of all stripes. He has reportedly labeled the Republican leadership in Congress as "c****s."

The timing of Clinton's speech may also be part of a strategy to thwart a potential move by Trump to the center on illegal immigration. Trump has reportedly canceled a Thursday speech in which he would detail a fuller plan regarding illegal immigration, amid news that he had softened his tone on the issue. Illegal immigration is a top issue for the alt-right and any attempt by Trump to moderate his message could be met with hostility from within his own ranks.

By placing a spotlight on the alt-right, Clinton likely hopes to make it harder for Trump to distance himself from the racialist elements of his support nationwide.
