Yes or true
No, he was a Representative for 25 years but never a Senator. As Vice-President, he was President of the Senate but never an elected Senator.
Obama was never a governor. He was the junior senator from Illinois.
Senator Kennedy has never taken a Senate salary. He declines it. A pretty generous gesture on his part.

He was never the governor of Illinois. He was in the Illinois state senate for three terms, and then he became a U.S. senator.
Assuming that you are referring to Joseph McCarthy, the notorious anti-Communist Republic Senator in the 1950s, then Truman never fired him. As a member of Congress, McCarthy was elected (from Wisconsin), and could not be fired by a President.
Garfield was elected to nine terms as a US Congressman . He was elected to the Senate the year he was elected President and so never served in the Senate. He was also a state Senator in Ohio.
He never was officially appointed emperor. He was assassinated at the Senate before they declared him Supreme Ruler.
A senator is never "appointed" president. He may be elected President of the U.S., in which case he must leave the Senate before taking office as President. In this case his successor is selected in accordance with the law of the state from which he came. Some states require a special election to fill the seat very quickly; others permit the Governor to appoint a successor who serves until the next general election (usually 2 years or less away) in which a successor will be elected to serve the reminder of the former senator's term. A senator may also be elected President pro tempore of the Senate. In this case he remains a senator but presides over the Senate in the absence of the Vice President who is also the President of the Senate.
Sam Houston was never US President, but he was the first and third president of the Republic of Texas, US Senator when Texas joined the US, and ultimately Governor of Texas. He did not serve consecutive terms as president, because the Constitution of the Republic of Texas prohibited that.
The original Equal Rights Amendment was written in 1923 by a leader of the Suffrage Movement, Alice Paul. It was introduced and passed the House and Senate in 1972 but was never ratified.
Julius Caesar was never a senator. He fought a civil war against the forces of the senate and won. When he became the ruler of Rome he turned the senate into an instrument for his power. He replaced senators who died when they fought in the civil war with his supporters. He also increased the size of the senate from 600 to 900 and filled the new seats with his supporters.
