Who is Stephen Miller? Trump's longtime aide gets top White House job

In a significant shift, Donald Trump named Stephen Miller as the new White House chief of staff, a decision that has generated alarm among Democratic lawmakers. Known for his contentious stance on immigration, Miller's rise could escalate tensions on Capitol Hill. Since the 2016 election, he has been instrumental in crafting Trump's domestic policies, which have attracted public criticism and may lead to enhanced Congressional investigations into the current administration.
