House Republicans have proposed punishing representatives who shoot video or take photos on the floor of the chamber — a change in rules seen as a direct response to a dramatic sit-in in June by House Democrats demanding a vote on gun control legislation that was streamed live online. The new policy would result in members of Congress being fined up to $2,500 for digital photography, audio or visual recording or broadcasting on the House floor. A GOP leadership aide said the rule changes are prospective and would only apply to future breaches of decorum. 'Bring.It.On.' California Rep. Eric Swalwell, a Democrat who was a leading figure in the June sit-in, tweeted in response to the new proposal.
