It's Wednesday, Jan. 2, 2019. Here's what you need to start your day:
1. Trump invites congressional leaders to White House as shutdown continues
The federal government has been partially shut down for 12 days.
Majority Leader Kevin McCarthy is expected to hand over House speakership to Nancy Pelosi on Wednesday, meaning virtually no legislation will get passed in Washington without her say-so.
Since Pelosi last sat down Senate Minority Leader Chuck Schumer and President Donald Trump to discuss a potential shutdown, the two sides have not spoken directly.
ABC News' Tara Palmeri says the president has invited top Democrats to the White House on Wednesday to discuss border security.
2. Warren forms exploratory committee for 2020 presidential run
On the final day of 2018, Massachusetts Sen. Elizabeth Warren announced she was officially forming an exploratory committee for a presidential campaign.
Now she's announced she'll be in Iowa this weekend, a place she'll presumably be quite often over the next 13 months leading up to the first caucus of the campaign.
ABC News Deputy Political Director MaryAlice Parks says the president likes a potential matchup with Warren.
3. American citizen accused of spying arrested in Russia
Russian authorities have arrested a man they say is an American spy on Russian soil.
According to a statement put out by Russia's Federal Security Service, a U.S. citizen named Paul Whelan was detained on Dec. 28 "in the course of committing spy activity."
Whelan, who is the head of global security for American auto parts supplier BorgWarner Inc., is also a former Marine.
ABC News Foreign Editor Kirit Radia spoke to Whelan's family, who say they don't believe he was involved in anything suspicious and are concerned about his well-being.
4. Toddler injured by rhino during Florida zoo experience
A small toddler was injured Tuesday after falling into a rhino exhibit at the Brevard Zoo in Melbourne, Florida.
The child fell during the "Rhino Encounter," a "hands-on, educational experience with Brevard Zoo's white rhinoceroses," Brevard Zoo said in an emailed statement to ABC News, adding that the program has been operating since 2009 without incident.
The incident comes just days after an intern cleaning a lion enclosure at a North Carolina animal center was killed by the animal.
ABC News' Stephanie Ramos has been talking to people living near the center who say they voiced their concern about its safety.
