House Minority Leader Nancy Pelosi, (D.-Calif.), gave an eight-hour speech from the House floor yesterday. She began her speech shortly after 10 a.m. and ended after 6 p.m., which became a congressional record regarding a floor speech.
The media was correct in reporting it was a floor speech, not a filibuster, because a filibuster occurs when there is a bill being voted on and considered on the House floor. CNN  and ABC News  correctly reported the background of the speech.
Pelosi spoke in opposition of a recent Senate deal reached between Democrats and Republicans to fund the government, which did not include any immigration provisions (primarily, legal status for ‘Dreamers,’ or those authorized to be legally in the U.S. due to one of President Obama’s executive orders).
