Here's a roundup of news trending across the nation and world today.

What to know now:

1. Health care vote: President Donald Trump decided the time for talking was over, according to the White House, when he let GOP leaders in the House know late Thursday that he wanted an up or down vote on a new health care package to take place on Friday. After a day of wrangling for votes, Trump said he was done working deals with those who said they would not support the legislation aimed at repealing and replacing most of the Affordable Care Act.

2. Cancer triggers: Scientists say that normal healthy cells in the body that make a "typo" when they multiply play a large role in who develops cancer. Researchers at Johns Hopkins University reported Thursday that about two-thirds of the mutations that are seen in cancers are random errors in the multiplication of cells. The scientists were quick to stress that while these "mistakes" are linked to the disease, many cancers are a result of risky behavior such as smoking, lack of exercise and a bad diet, and those can be prevented.

3. New iPad on sale: If you've had your eye on an iPad, today is the day you can place your order for Apple's newest version of the tablet. Plus, there's a bonus – it's cheaper than recent iPads. The new 9.7-inch screen version, which was unveiled earlier this week, starts at $329 and has up to 10 hours of battery life. It doesn't have all the bells and whistles of the 12-inch iPad Pro, but then it doesn't cost $799 either.

4. CIA hack of iPhone, Mac: A release of documents from WikiLeaks suggest the CIA has a program that can be used to hack into iPhones and Mac computers. The technique, according to cyber security experts, is one that involves an older model of the devices, and generally requires some physical access. "The most notable part of this latest WikiLeaks release is that it shows the CIA doing exactly what we pay them to — exploit specific targets with limited attacks to support our national interests," Rich Mogull, CEO of the security research firm Securosis, told The Associated Press.

5. London terror attack: The man who stabbed and ran over people in a terror attack in London this week was British-born and known to law enforcement authorities, according to officials in the United Kingdom. Khalid Masood, 52, was born Adrian Russel Ajao. He was a Muslim convert, according to some news reports, and was known to security services as "a peripheral figure, … not part of the current intelligence picture."

Disney head Bob Iger says the next movie in the "Star Wars" franchise, "The Last Jedi," will not be changed in light of the death of actress Carrie Fisher. "We had to deal with tragedy at the end of 2016. Carrie appears throughout VIII ("The Last Jedi"). We are not changing VIII to deal with her passing. Iger said fans could see "another decade-and-a-half of "Star Wars" stories" come to the big screen. "Rogue One: A Star Wars Story" is available on Google Play, as of Friday. It is priced at $19.99. The movie will be available on Blu-ray on April 4.
