(CNN) - In case you haven't tuned into C-SPAN Friday, you might have missed that Sen. Bernie Sanders has been talking. And talking. And talking.
Summoning his inner Frank Capra, the Vermont independent has been speaking on the Senate floor virtually non-stop since 10:24 a.m. ET - all in an effort to show his opposition to the temporary extension of the Bush-era tax cuts that President Obama and Republicans have agreed to.
Is Sanders filibustering?
The Senate parliamentarian's office says no. The Senate is technically in a period of Morning Business - time set aside during any part of the day for senators to deliver speeches on any subject that they want - and therefore not technically debating the bill.
Senate Majority Leader Harry Reid's staff - which runs the floor - also says it's not a filibuster.
Even Sanders admits it's not a filibuster, starting his oratory with, "You can call what I am doing today anything you want. You can call it a filibuster. You can call it a very long speech. I am not here to set any great records or to make a spectacle. I am simply here today to take as long as I can to explain to the American people the fact that we have got to do a lot better than this agreement provides."
Though not technically a filibuster, the move adds a dramatic picture to just how strongly some members of Obama's own party are against the deal he reached with Republicans earlier this week that extends the tax cuts for all income levels. Sanders normally caucuses with Democrats.
A spokesman from Sanders' office says there is no timeframe for when the senator will wrap up, although the Senate is not due to convene this weekend.
An email from Sanders' office reported that the Senate video server temporarily shut down because more than 12,000 users were trying to watch the speech.
Sanders' staff, by the way, referred to his speech as a "filibuster."
Sanders has many hours to go however if he wants to set records. The longest Senate floor speech was delivered by the late Sen.
Strom Thurmond of South Carolina in 1957 when he spoke for 24 hours and 18 minutes in opposition to the Civil Rights Act that year.
A vote to begin debate in the Senate on the measure is scheduled for Monday.
UPDATE: After speaking for eight hours and thirty five minutes, Sanders finally yielded the floor at 6:59 pm.
