No! I don't mean that either. You are correct in saying two wrongs don't make it right. National Security should be taken just as seriously regardless and what happens in one, prior, the administration doesn't mean the next or the following one gets a pass on its responsibility.
If there are known errors or problems them they need to be addressed but here is where I believe my comment becomes more valid. If past offenses are uncovered, discovered, and proven, then just becausethere is a new administration doesn't mean that there should be any less concern over the problems. If there were offenses, deliberate offenses, that put National Security at risk, potentially exposed, our National secrets, then they do not all of a sudden get a pass because they are no longer in power.
If National Security is a problem, now, then it should also be a problem warranting condemnation and investigation by those willing to condemn it, now, and investigating it now, except extending it back to those who may be guilty, from a prior administration. I'm just saying if it's important enough to report on it now, consider it an offense worthy of investigating now, then it's worthy to resurrect offenses that are known to have happened under the Obama administration. That's not to say Obama knew directly of those offenses just as it's reasonable to assume that Trump didn't know either. Presidents do delegate authority and certain task to subordinates who don't always make the best and right decisions so it's possible that a President would not know everything about all of the people that are hired in their administration in various positions.
Also, like the Obama administration, there are those that want to find a reason to find fault with the President but what is unlike the Obama administration and Presidency is the level, the height, and the zeal to which people are attempting to bring down Trump or report negatively upon him or his administration. Conservatives hated Obama, would have loved to gotten rid of Obama and loved to have found a way to do just that such as if they could locate or prove a faked birth certificate, but they couldn't. There was an effort but not near to the degree of the efforts being leveled against Donald Trump.
Many Conservatives and people, including Trump, took a lot of heat over Obama's birth certificate challenge but there was never the vitriol and animosity, the negative reporting toward Obama, that is leveled at Donald Trump and for no other reason than he is Donald Trump and he won an election that apparently was promised or guaranteed to Hillary Clinton, by the polls, by the media, and by the Democratic National Committee.
An election that was so skewed and slanted to favor Hillary Clinton and guaranteeing her election by everyone but the voters who, in the end, chose Donald Trump. You can only look at it one way and that is that she was such a horrendous, horrible, candidate that she couldn't even bring home an election that was so skewed in her favor even to the point of being provided questions from the debates so she could prepare the best responses. The media, also, had a full court press on, so to say, from the time Donald Trump won the Republican convention and was certified as the Republican candidate to find things and report things to destroy his candidacy or chances to be elected along with concealing anything appearing negative with regards to Hillary Clinton, at least that they could control.
What the media and the Democrats couldn't control, however, was Hillary's untrustworthiness and her horrible candidacy, decisions like passing over certain states altogether during her campaign. Her being Hillary, her emails, and their deletion, and the Benghazi problems that dogged her, calling the relatives of those killed liars for revealing what she actually told them regarding the deaths of their kin, her lies about the cause of the attack and attributing it to the YouTube video to avoid the political fallout to the, then, Obama administration at the time of his re-election. Hillary was not only a horrible candidate but she had a huge amount of negative baggage that helped do her in.
