Sorry for the short notice on this one, it was announced this morning but I just found out now.
8 PM Eastern / 5 PM Pacific, from the Oval Office. Biden speaking, presumably about the Trump assassination attempt.
Video here of the earlier conference, still looking for the Oval Office speech.

Oval Office speech here:
I say it sarcastically, but not without a hint of truth behind it. With the current political leanings of the Supreme Court, if Biden ever tried to off a political opponent as an official act, they would probably call for him to be impeached and hung for treason. If a republican did it, they would likely throw a pizza party and declare the act a necessity to preserve American politics.
