Jeff Sessions uses bullshit excuse to not answer the Senate's questions

Jeff Sessions essentially refused to answer questions about Russia and his conversations with Donald Trump regarding the firing of James Comey during his Senate testimony under oath arguing that he was honoring a tradition of confidentiality between the Department of Justice and the president. Problem is, there is no law or legal standard that justifies that bullshit excuse. And the Senate told him. Sessions then goes on to say that he's not answering the question in case Trump wants to use executive privilege. In other words, there's no reason for Sessions to refuse to answer:

King boxes Sessions in. Sessions says he's not answering Qs because Trump may eventually invoke executive privilege. https://t.co/P07OKLYV1I

So not only Sessions is in contempt of the Senate, but he could be potentially obstructing a Congressional investigation. And there's no legal reason for him to do so.
