Democratic senators are sick and tired of being thwarted in their efforts to address gun violence, and led by Sen. Chris Murphy, they’ve been holding the Senate floor with a filibuster to demand change.

You can watch the filibuster live here:

“There is a fundamental disconnect with the American people when these tragedies continue to occur and we just move forward with business as usual,” Murphy said. “So I’m going to remain on this floor until we get some signal, some sign that we can come together on these two measures, that we can get a path forward on addressing this epidemic in a meaningful bipartisan way.”

On social media, people are expressing their profound gratitude to Murphy and his colleagues for taking a stand.
