President Trump is claiming power over independent agencies and trying to redirect the administrative state, saying he is its unitary executive. But this is not the first time presidents have invoked broad authority. John Dearborn finds that President Reagan sought to gain power over civil rights agencies, saying they had gone too far in promoting affirmative action, restricting their activity and disciplining their leadership. Multiple current Supreme Court justices were involved in the saga, which helped build the unitary executive theory. David Hausman researches attempts to control the immigration courts under the first Trump administration, finding that both adding judges and setting precedent with Attorney General opinions were influential. But it mostly worked by building the bureaucracy, rather than restraining it.
