House Democrats on Wednesday plan to stage a "national day of action" against gun violence that will feature "family sit-ins," House Minority Leader Nancy Pelosi, D-Calif., announced. Pelosi said the action would "carry forward the momentum" from the Democrats' takeover of the House floor last week. Democratic lawmakers staged a 25-hour sit-in which included attempts to disrupt the floor schedule and votes. They demanded the GOP leadership allow consideration of two gun control bills, but relinquished the floor hours after the GOP adjourned the House for a week-long recess.
