The purpose of the word “otherwise” in Section 1512(c)(2) is therefore to clarify that the provision covers obstructive acts other than the destruction of physical evidence with the intent to impair its integrity or availability, which is the conduct addressed in Section 1512(c)(1). The word “otherwise” does not signal that Section 1512(c)(2) has less breadth in covering obstructive conduct than the language of the provision implies.
