- Pennsylvania Democrat John Fetterman is calling on New Jersey Sen. Bob Menendez to resign.
- Fetterman said his colleague, facing corruption charges, shouldn't "wield influence" in the Senate.
- Menendez has resisted calls to step down, saying he is "not going anywhere."
Worried about their slim majority, Democratic leaders in the Senate have thus far resisted joining the chorus — including members of their own party — demanding that New Jersey Sen. Bob Menendez step aside over allegations that he corruptly served the interests of a foreign power.
