Marco Rubio told reporters in a hallway interview he wants the intelligence committee to investigate Trump's short-lived National Security Advisor Mike Flynn, although he isn't sure Flynn should testify. He also aired the progress of the Russian hacking probe.

On why the intelligence committee should run Flynn probe: "I think it's the best forum for it. It's set up, it's ready to go, it has the staff, it has by-partisan buy-in. I imagine other committees would want to look at it too." He said "I'll be upset and I'll let you know that I don't think it was a worthy effort" if the investigation isn't done seriously.

On Russian election hacking investigation: "Work has begun, yes. I'm not going to go into detail about how far they've gotten."

Joe Biden twice referred to President Trump as "this guy," and Trump called the former vice president's family "like a vacuum cleaner" for foreign money.

Why it matters: The personal venom — during Thursday's final presidential debate, in Nashville — was a reminder that even during a more normal debate, nothing this year is normal.

A surprise offer from Vladimir Putin has the U.S. and Russia once again circling a potential pre-election nuclear deal.

The big picture: The last treaty constraining the U.S. and Russia, New START, is due to expire on Feb. 5, 2021, two weeks after the next U.S. presidential inauguration. For the first time since the height of the Cold War, the nuclear guardrails could come off.
