The third day of the U.S. Supreme Court conducting oral arguments by telephone because of the Coronavirus outbreak brought another piece of history for the High Court - as the live broadcast seemed to feature one of the participants flushing a toilet.

The sound came out as Roman Martinez, counsel for the American Association of Political Consultants was making his arguments in the second case of the day before the U.S. Supreme Court.

"What the FCC has said is that when the subject matter," Martinez said - as one can hear what seems to be the clank of a toilet flush, followed by the sound of rushing water.

The discovery was first noted by Nicole Ninh, a producer for C-SPAN.

And sure enough, that's what seems to have happened.

Jeremy Art of C-SPAN swiftly got the potty audio uploaded on Twitter.

The toilet audio starts at about the seven second mark of this tweet.

Luckily, there does not seem to have been any audio of the actual use of the bathroom by the unidentified person.

Those with the ability to have their voice heard on the oral arguments would seem to be limited to the nine Justices, the attorneys on each side, and maybe some Supreme Court officials.
