The Hill notes that "at least one lawmaker used the new rules in the House to tweet from the House's floor.
"Rep. Ileana Ros-Lehtinen (R-Fla.) sent dispatches from the House floor, taking advantage of new rules — which, at that point, had not yet been approved — allowing members to use BlackBerrys and other electronic devices in the chamber.
"Ros-Lehtinen dispatched several tweets, one of which included a photo, proving that she was tweeting from the floor: Speaker Pelosi hands over the gavel to Speaker Boehner: hurrah!!! http://yfrog.com/h096367147j
"The Republican-led change in rules lifted a previous ban on the use of electronic devices on the floor."
