That is far too vague and ambiguous a charge for anyone to seriously argue it rises to the level of an impeachable offense. What is required is a high crime that is comparable to treason or bribery. Assuming that the worst charges against the President are true and convincing, his alleged misconduct does not rise to that level. Indeed, there is not clear and persuasive proof that the President committed any crimes. Those who would impeach the President have tended to use important words cavalierly and interchangeably as if they have fungible content.
Words have meaning, they are the skins of living thoughts.
To mislead, to lie, to perjure oneself are all, in varying but important degrees, wrong. But to mislead is not necessarily to lie, to lie is not necessarily to perjure. Unfortunately, words can be and have been used interchangeably and carelessly, leading to obfuscation or confusion. Some who favor impeachment have too frequently used them to manipulate rather than to clarify. Some believe that the President committed perjury.
