steve bannonSteve Bannon, the White House’s chief strategist and former Breitbart executive chairman, Goldman Sachs executive, Hollywood producer and Navy officer, has emerged as one of the most powerful voices in the early days of the Donald Trump administration. During the campaign and after the election, Bannon was widely criticized for his ties to the Alt-Right, his ex-wife’s accusations of anti-Semitism, and reportedly nativist views. Now that the Trump administration has taken power, Bannon’s role is starting to become clear. Here’s what we know so far.

He called the media “the opposition party.”

He reportedly overruled Homeland Security lawyers during the creation of Trump’s travel ban.

He has been added to National Security Council despite having no military or foreign-policy expertise.

He has eliminated some national security paper trails.

He allegedly called himself a “Leninist” and advocated the “destruction of the state” in 2013.
