For years Stephen Miller has been a conservative firebrand in Donald Trump's political orbit. Now, he has become a lightning rod.

His relentless, combative style at the policymaking helm of the White House has set the president's hardline immigration agenda in motion, and he has developed a growing influence in expanding US power across the Western Hemisphere.

The high-velocity start to 2026 by the Trump administration, at home and abroad, has only cemented his position as one of its most powerful figures.

But for many on the left, he is a villain.

In Washington DC, posters of Miller's face have been plastered in public spaces with the caption "Fascism ain't pretty". Democrats have called for his resignation. Even some members of his own party have publicly questioned his political judgement and effectiveness.
