Police: Austin suspect killed self with bomb 01:44

(CNN)There's big breaking news overnight in the bombings in Austin, Texas. Let's get straight to it -- and to 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. Austin bomber

The suspect in the Austin explosions blew himself up in his vehicle as police closed in, Austin Police Chief Brian Manley said just moments ago. Police started getting intel on the 24-year-old man, who hasn't been identified publicly, over the past 36 hours, and surveillance teams were on his trail, Manley said. His vehicle was found at a hotel in Round Rock, about 20 miles north of Austin. Police had it surrounded -- and were waiting for tactical teams -- when the suspect started to drive away, Manley said. His vehicle then suddenly stopped -- and the suspect detonated an explosive device, Manley said. One officer was hurt in the blast. 
    A serial bomber had terrorized Texas' capital all month, dispatching explosive packages around the area and killing two people. The main focus in the hours before the bombmaker's death had been an explosion early yesterday at a FedEx sorting center near San Antonio. Another unexploded bomb was found at another FedEx facility near Austin. Police said those two packages are connected to four previous bombings in the city.

    2. Trump & Putin

    President Trump made a call to congratulate a counterpart on his reelection. That's pretty ho-hum stuff, unless that counterpart is Russian President Vladimir Putin, who won what everyone considers to be a less-than-democratic race. Trump's own advisers warned him not to do it -- they reportedly wrote "DO NOT CONGRATULATE" in his briefing materials -- but Trump did it anyway. Because that's how this President rolls. The harshest critic of Trump's move was Sen. John McCain, who said, "An American president does not lead the free world by congratulating dictators on winning sham elections."

    3. Facebook & Cambridge Analytica

    These aren't the best of times for the world's fave social media site. Facebook suspended a scientist for collecting data on tens of millions of Americans. He passed the data on to Cambridge Analytica, a firm hired by Donald Trump's 2016 presidential campaign. The scientist, Aleksandr Kogan, said Facebook was just scapegoating him to deflect from its woes. "Using users' data for profit is their business model," he said in an exclusive interview with CNN.

    People are ticked about all the data-sharing, and some investors are suing Facebook over the scandal. A co-founder of WhatsApp even said it's time for everybody to delete Facebook (which owns WhatsApp, so that's awkward).

    4. School shootings

    A school resource officer is hailed as a hero, after his quick actions brought a swift end to a shooting at a high school in Maryland. Deputy Blaine Gaskill shot at a 17-year-old gunman who opened fire at Great Mills High School. The shooter died, though it's not clear if Gaskill killed him or he killed himself. Two other students were hurt in the shooting, one with life-threatening injuries.

    Meanwhile in Florida, authorities are trying to use the state's new gun law -- passed after the school massacre at Parkland -- to block Zachary Cruz's access to guns. Cruz, younger brother of the Parkland school shooter, was arrested Monday, accused of trespassing at Marjory Stoneman Douglas High School, where his brother killed 17 people.
    But that's not all that's been going on at Stoneman Douglas. Florida Gov. Rick Scott offered to provide extra security at the school after a deputy was suspended for appearing to fall asleep on duty, two students were charged for allegedly bringing weapons to campus and another student was charged for allegedly making a threat of violence on social media.

    5. Male birth control

    The world might be a lot closer to a birth control pill for men. A proposed hormone pill, called dimethandrolone undecanoate, effectively decreased testosterone levels and other hormones responsible for sperm production without serious side effects, a new study says. However, the study had a small sample size, so more research needs to be done on it.
