About 40 Democrats of the US House, led by Civil Rights veteran John Lewis, have occupied the House floor, about as close as they can get to the equivalent of a Senate filibuster. They are there to force a vote on gun bills.
Their timing is a bit off... the House is on break (thus the sit-in isn't being televised, and Speaker Ryan could let them sit there until the end of the break).
It is also true those bills have also been voted down in the Senate. But the goal here is also to prove to voters who is obstructing gun control and get their votes on record.
Yesterday I wrote that the GOP is pleasing their corporate masters by voting against sensible reforms. Another way to say that is the NRA is holding the GOP hostage. Cartoonist Keith Knight takes that idea literally.
