Momma knows best!

Rep. Keith Ellison (D-Minn.) learned just that when his mother called him and told him to join House Democrats' gun control protest on Wednesday. Dems staged a sit-in that continued into Thursday to demand action on gun violence.

Ellison joined the protest, spearheaded by Rep. John Lewis (D-Ga.). He live tweeted from the chamber -- even as Republicans cut cameras that had been broadcasting the event.

Congress is officially out of session until July 5th, but Democrats said they'd occupy the floor until Republicans agree to engage in a meaningful debate about gun control.

Senate Democrats staged their own protest last week, filibustering a bill to fund the Justice Department until Republicans agreed to consider new gun control measures. All of the proposals were ultimately rejected.
