The Senate plans to begin voting at 4 p.m. Wednesday on nine amendments to its gun safety bill, amendments that deal with a wide range of gun control and gun rights issues.
Each vote will last 10 minutes, and there will be two minutes of debate equally divided between each side before each vote.
It's not clear when a final vote on the bill will be taken.
First vote is expected to come on a stronger background check measure, a compromise pushed by Sens. Joe Manchin, D-W.Va., and Pat Toomey, R-Pa.
Then will come amendments on gun traffricking, extending conceald carry laws, banning assault weapons, limiting the size of magazine clips and more.
