It's Monday, Dec. 2, 2019. Let's start here.
1. London terror
Police in London say the suspect accused of killing two and injuring three others in a stabbing attack near London Bridge on Friday was a convicted terrorist who was released in 2018.
Police shot and killed Usman Khan after bystanders subdued him using a fire extinguisher and a narwhal tusk from a nearby bar.
ABC News Senior Foreign correspondent Ian Pannell explains that many are calling for a change to the law that allowed Khan to be released early: "The reality will still be the legal system as it currently stands means people will be allowed out at some point. You can't lock people up indefinitely."
2. Can I get a witness?
"As for the hearing scheduled for December 4, we cannot fairly be expected to participate in a hearing while the witnesses are yet to be named and while it remains unclear whether the Judiciary Committee will afford the President a fair process through additional hearings. More importantly, an invitation to an academic discussion with law professors does not begin to provide the President with any semblance of a fair process. Accordingly, under the current circumstances, we do not intend to participate in your Wednesday hearing," White House counsel Pat Cipollone wrote in a Sunday evening letter to Chairman Jerry Nadler.
ABC News' Katherine Faulders tells "Start Here" that House Republicans continue to back up the White House in this debate: "They've accused Democrats of blocking their due process rights. Well, they won't be showing up for this on Wednesday."
3. Trump's Afghanistan surprise
During his first visit to Afghanistan, Trump announced on Thanksgiving that peace talks with the Taliban had been reignited.
ABC News' Elizabeth McLaughlin explains to "Start Here" that the Taliban’s refusal to talk to the Afghan government remains a big sticking point.

Doff your cap:
Pop stars often get plenty of bad press, but Sia proved over the holiday weekend that she's no diva.
The "Chandelier" singer, who's not even from the U.S., nonetheless was in the Thanksgiving spirit as she picked up the check for everyone at the registers at a Walmart in Palm Springs, California, on the holiday.
Of course, most of the shoppers had no idea who she was at first since she famously covers her face during performances.
