The Senate rejected a bipartisan compromise amendment to expand gun background checks on Wednesday, casting a 54 to 46 vote that drew sharp responses from supporters who had seen the measure as a small, significant and viable step forward on gun control.
"All in all, this was a pretty shameful day for Washington," President Barack Obama said, addressing the inaction. Standing behind the president was former Rep. Gabrielle Giffords (D-Ariz.) who moments before had also lambasted senators for their opposition in an email.
Below, a list of the Twitter handles of all of the senators who voted no on the measure, excluding Senate Majority Leader Harry Reid (D-Nev.), who voted against the amendment on procedural grounds. Find their information and let them know how you feel.
