'Trump’s move on Tuesday aims to take that singular remedy off the table. If he succeeds—if impeachment is delegitimized and ignored—then Trump, and future presidents, will be truly above the law.'By calling the impeachment inquiry unconstitutional, Trump has ignored reality to place himself above the law.The Justice Department has long taken the position that a sitting president cannot be indicted. The reasoning behind the Justice Department’s policy is that impeachment is the constitutional remedy for presidential wrongdoing and that impeachment is a political process, not a legal one. In a recent lawsuit he filed to block the Manhattan district attorney from examining his taxes, Trump pushed this theory to the breaking point. Trump asserted that not only is he safe from indictment, he cannot even be investigated while in office.'
