President pro tempore of the United States Senate

“ No person shall be a senator who shall not have attained to the age of thirty years, and been nine years a citizen of the United States, and who shall not, when elected, be an inhabitant of that State for which he shall be chosen.
The vice-president of the United States shall be president of the Senate, but shall have no vote, unless they be equally divided.
The Senate shall choose their other officers, also a president pro tempore, in the absence of the vice-president, or when he shall exercise the office of president of the United States. ”

“ I hope we can strengthen it further in the Senate. What we can't do is drag our feet or delay much longer. The American people expect us to act, and that's exactly what I intend to do as President of the United States. ”

“ The United States Senate does not work that way, nor can it, or should it.
Mayors, governors, and presidents can sometimes succeed by the sheer force of their will. But there has never been a Senator so persuasive, so charismatic, so clever, or so brilliant that they could make a significant difference, while refusing to work with other members of this body.
Simply put, Mr. President, Senators cannot ultimately be effective alone. ”
