'Start Here': Brexit, Barr, Nairobi. What you need to know to start your day.

It's Wednesday, Jan. 16, 2019. Thanks for choosing to start here.

1. Barr's confirmation hearings

President Donald Trump's pick to lead the Justice Department, William Barr, faces a second day of questioning on Capitol Hill after vowing on Tuesday to protect special counsel Robert Mueller's investigation.

"I believe it is in the best interest of everyone -- the president, Congress and, most importantly, the American people -- that this matter be resolved by allowing the special counsel to complete his work," he said during his confirmation hearing, adding that he's known Mueller 30 years.

Barr, who previously served as attorney general from 1991 to 1993, was grilled on topics related to the Mueller probe, at one point defending the special counsel against the president's claims the whole thing is a witch hunt.

ABC News' Mike Levine tells us Barr is expected to be confirmed: "I just don't see this nomination being blocked."

2. Brexit vote fails

Last night, a Brexit vote in British parliament failed by a vote of 432-202, leaving the country in a state of uncertainty 10 weeks before it's set to leave the European Union.

ABC News Foreign Editor Marcus Wilford explains that Prime Minister Theresa May likely will stay on as prime minister, even if a confidence vote is undertaken.

3. American among dead in Nairobi attack

Multiple people were killed in a terror attack in Nairobi, Kenya, as gunmen stormed a luxury hotel complex on Tuesday.

Emily Johnson, a freelance reporter who covers Africa, recounts the "tense scene" as everything unfolded: "We could hear gunshots occasionally, as well as a blast, a pretty loud blast, as another car bomb went off."

An American was among those killed, the State Department confirmed in a statement condemning the "senseless act of violence" at the upscale Dusit hotel.

Al-Qaeda-linked terror group Al-Shabab claimed responsibility for the attack.

How Kirsten Gillibrand could win the 2020 Democratic primary: Gillibrand is one of several Democratic women expected to run, and her campaign will make its central appeal to women voters. But given the oft-times gendered dynamics of the 2016 presidential campaign, Gillibrand is likely to face challenges because of her gender and her vocal support of the #MeToo movement.

How 17 long-shot presidential contenders could build a winning coalition: It might seem obvious that having a wide-open field, as Democrats have for their 2020 presidential nomination, would make it easier for a relatively obscure candidate to surge to the top of the polls. But I'm not actually sure that's true.
