The Executive Branch and its Ties to the Justice Department

The Executive branch of US government is seemingly the most complex and complicated of the three branches. The Executive branch's powers are limited when compared to the other two branches, however the President is viewed as the most powerful person/position in government by the public. The Executive branch's constitutional powers include granting pardons and reprieves for federal crimes, however following the Watergate scandal Edward Levi and Griffin Bell implemented changes to the Justice Department to separate law from political influence. According to Bell and Levi, the law was meant to be neutral and nonpartisan, and in order to achieve that standard, the President must abide by the rule of law and lack involvement in criminal prosecutions. In the past and now again with Trump as President, there has been an infringement on this separation- with the President using his power to abuse the rule of law by forcing his way into cases exclusively meant for the Justice Department. This appears to be an example of the stewardship theory- where the President believes he is able to exert any power that is not express prohibited by the Constitution, if it is in the nation's best interest. In Trump and Nixon's case, they saw the law as an instrument they could bend for power (and because they had power), instead of justice. With all of his ties to Russia and the ongoing investigation with Russia, Trump has been pushing the limits Bell and Levi have put in place. For example, when it comes to the Russia investigation, Trump is using the law in a biased fashion- in a way that he believes will help himself and his case. Trump has "personally intervened to try to lift a gag order on an undercover FBI informant sought by Republican members of Congress in an investigation of Russian nuclear industry efforts to gain influence in the United States during the Obama administration". Trump has continually interjected himself in political law enforcement issues, interacting heavily with the Justice Department, attorneys and the FBI (i.e. the Robert Mueller case). This is clearly not following Bell and Levi's advice to keep the Department of Justice neutral and separate. The Department of Justice is an agency within the Executive Branch, and the Executive Branch is responsible for regulating and overlooking the Department of Justice. Of course, the Department of Justice has jurisdiction apart from the Executive Branch, but with the intermixing of politics and law stemmed from the President's actions, that power can be diminished. The President should not use his overall, Executive power to intervene on issues meant only for the Department of Justice just because he deems that he has the power to do so- it will muddle the boundaries between politics and law, and we have Watergate as proof.
