According to Wiki's sources, the Deep State is government bureaucracy and establishment politicians...
"...In the United States the term "deep state" is used within political science to describe influential decision making bodies within government that are relatively permanent and whose policies and long-term plans are unaffected by changing administrations. The term is often used in a critical sense vis-à-vis the general electorate to refer to the lack of influence popular democracy has on these institutions and the decisions they make.[1][2] The term was originally coined in a somewhat pejorative sense to refer to similar relatively invisible state apparatus in Turkey and post-Soviet Russia.[3] With respect to the United States, the concept has been discussed in numerous published works by Marc Ambinder, David W. Brown, Peter Dale Scott, Mike Lofgren, Kevin Shipp and Michael Wolff.
While definitions vary, the term gained popularity among various groups, primarily supporters of Donald Trump, Bernie Sanders, and conspiracy theorists, during the 2016 U.S. presidential election, in opposition to establishment Republican and Democratic candidates. Since Trump's inauguration, the term has been used by commentators who argue that a 'deep state', involving the FBI, CIA, NSA, former President Barack Obama, and/or Hillary Clinton, is aiming to delegitimize the Trump presidency and thwart its policy goals.[4][5]...."

It goes on to say that Breitbart and Trump supporters have appropriated the term to support their conspiracy theory narratives....
"...The term has been appropriated by Breitbart News and other conservative and right-wing news outlets, where supporters of the Trump Administration have used it to support a variety of conspiracy theories.[11] It has been dismissed by authors for The New York Times[4] and The Observer.[12] University of Miami Professor Joseph Uscinski says, "The concept has always been very popular among conspiracy theorists, whether they call it a deep state or something else."[13]..."
