Still can't connect with folks on Facebook? The social media giant says what could be its biggest outage ever should end this morning. Here's what else you need to know to Get Up to Speed and Out the Door. (You can also get "5 Things You Need to Know Today" delivered to your inbox daily. Sign up here.)

1. Ethiopian plane crash

Similarities between deadly Ethiopian Airlines and Lion Air crashes has led to the grounding of all Boeing 737 Max planes in the US. The FAA said these similarities were found in data gleaned from satellite-based tracking. So, the planes will stay out of US skies indefinitely, pending an examination of Ethiopian Airlines Flight 302's black boxes. That will take place in Paris, where the black boxes are expected to arrive today. The US was the last country to ground the planes. US officials and Boeing had argued to keep the planes operating but changed course in light of this new information. Meanwhile, the world continues to mourn the victims of this international tragedy, including a woman traveling on the ill-fated flight with her family who sent a message to her sister, saying she felt "like there's something bad ahead."

2. Politics

The news is breaking fast and furious in the political world, so let's handle it lighting-round style:

The Senate votes today on a resolution of disapproval that would block President Trump's national emergency declaration on the US-Mexico border. It's expected to pass. Trump vows to veto it.

Paul Manafort was sentenced to 43 more months in prison on federal conspiracy and obstruction charges. So, that's a total of 7.5 years behind bars for Trump's ex-campaign chairman, who'd already been sentenced on financial convictions in Virginia. Then, just moments after the latest sentence was handed down, the Manhattan district attorney charged Manafort with business and mortgage fraud allegations.

An attorney connected with Trump lawyer Rudy Giuliani reassured ex-Trump fixer Michael Cohen in an email back in April that Cohen could "sleep well tonight" because he had "friends in high places," a copy of an email obtained by CNN shows. Cohen presented this and another email during his closed-door congressional testimony as proof that a pardon was dangled before he cooperated with prosecutors. But the lawyer who wrote the emails called Cohen's interpretation "utter nonsense."

Make room for one more in the crowded Democratic presidential field. Beto O'Rourke announced his candidacy this morning. He's starting a three-day swing through Iowa today.

3. Brexit

It's another day of Brexit voting in London, after lawmakers yesterday rejected the option of a no-deal Brexit. Parliament will vote today on whether Brexit should be postponed for a couple of months to give everybody more time to figure this out. But even if this vote passes, there's no guarantee that the European Union would agree to a Brexit delay without some kind of withdrawal deal already in place. And UK lawmakers have already rejected embattled Prime Minister Theresa May's proposed deals twice. The UK is set to leave the EU in just weeks. Click here to keep up with the latest updates.

4. College admissions scandal

The University of Southern California says all applicants tied to the biggest college admissions scam ever alleged won't be allowed to attend the school. The status of students already enrolled at USC who might be connected to the scheme will be reviewed on a case-by-case basis. That's the latest fallout from the nationwide scandal, in which 50 people -- including wealthy parents, actresses, college coaches and test administrators -- are accused of using bribes and cheating on tests to get students into top-notch colleges. Many people of color and those from disadvantaged backgrounds say the scandal shows that it's not affirmative action that threatens the fairness of the college admissions process but the advantages of the rich and powerful.

5. Weather

The bomb cyclone hit hard. It whipped Rocky Mountain and Southwestern states with hurricane-force winds. It caused blizzard conditions in Colorado that sparked a 100-car pileup and stranded about 1,100 motorists on the roads. It left 125,000 people without power in Colorado and Texas. It closed Denver's airport and canceled almost 3,100 flights nationwide. It caused flooding in Iowa, Illinois and Missouri. And it's bringing the threat of tornadoes to the central US. Click to find out where the storm is headed next, to see pictures and to learn just what exactly a bomb cyclone is.
