What does it mean that a senator sponsors or co-sponsors a bill?

Answer:

Sponsoring and Co-Sponsoring a bill is similar to Moving or Seconding a motion in a committee. Essentially, the Sponsor and Co-Sponsor(s) are the persons who are actually bringing the bill before the Senate (or House) and asking for it to be considered.
