Britain's information commissioner says she is using all her legal powers to investigate Facebook and political campaign consultants Cambridge Analytica over the alleged misuse of millions of people's data.
Commissioner Elizabeth Denham is pursuing a warrant to search Cambridge Analytica's servers. The company allegedly used data mined from Facebook to help Donald Trump win the 2016 presidential election.
She told BBC on Tuesday she is also investigating Facebook and has asked the company not to pursue its own audit of Cambridge Analytica's data use. She says Facebook has agreed.
"Our advice to Facebook is to back away and let us go in and do our work," she said.
Student Terrence Rhames, 18, witnessed the shooting at Great Mills High School in Maryland as he waited for his first class to start Tuesday morning.
Battles over priorities in a huge government-wide spending bill are essentially settled, leaving a scaled-back plan for President Donald Trump's border wall and a huge rail project that pits Trump against Capitol Hill's most powerful Democrat as the top issues to be solved.
A hoped-for agreement didn't materialize overnight but could be announced as early as Tuesday.
The measure would provide major funding increases for the Pentagon — $80 billion over current limits — bringing the military budget to $700 billion and giving GOP defense hawks a long-sought victory. Domestic accounts would get a generous 10 percent increase on average as well, awarding Democrats funding wins that eluded them during the Obama administration.

Melania Trump pushed back against critics Tuesday, declaring her commitment to combating cyberbullying despite the hits she has endured for taking on the issue while her husband routinely goes on Twitter to berate foes and call them names.
"I am well aware that people are skeptical of me discussing this topic," the first lady said. "I have been criticized for my commitment to tackling this issue, and I know that will continue. But it will not stop me from doing what I know is right. I am here with one goal: helping children and our next generation."
A judge has set bond at $500,000 for the younger brother of suspected school shooter Nikolas Cruz after he was arrested for trespassing at the Florida high school where 17 people were gunned down.
Judge Kim Theresa Mollica set the hefty bond for Zachary Cruz and ordered him to take a psychological evaluation one day after he was arrested for allegedly trespassing at Marjory Stoneman Douglas High School.
Prosecutor Sarahnell Murphy had sought a $750,000 bond and said he "has all the same flags present as his brother." She also said Cruz did not give his true address when he was arrested.

When the Trump administration abruptly canceled a federal teen pregnancy prevention program last year, it did so over the objections of career experts in the Department of Health and Human Services, according to internal notes and emails obtained by NBC News.
Three political appointees with pro-abstinence beliefs guided the process in spite of the the objections, according to the cache of documents. The notes show that Evelyn Kappeler, the $213 million Teen Pregnancy Program's long time administrator, appears out of the loop on decisions and describes being "so rattled" at one point that her reaction "was to cry."
Many medical professionals credit the program, which had bipartisan support in Congress, with lowering the national teen pregnancy rate to its lowest point. An outside group claims the effort to end it violated a federal law.

A survivor of last month's shooting at a Florida high school that left 17 people dead said he and fellow students must use their "white privilege" to offset the racial disparity in the way news media covers gun violence.
Speaking during a Twitter Q&A livestream Monday with fellow Marjory Stoneman Douglas High School students, senior David Hogg said Parkland shooting survivors must use their platform to make sure the stories of other students across the country who experience gun violence are also heard.

The company behind the golden arches wants to get greener.
McDonald's on Tuesday announced a number of steps it will take to cut the greenhouse gases it emits into the air, including tweaking the way the beef in its Big Macs and Quarter Pounders is produced.
The world's largest burger chain said it expects the changes to prevent 150 million metric tons of greenhouse gas emissions from being released into the atmosphere by 2030, equal to taking 32 million cars off the road for a year.
The Weinstein Co. filed for bankruptcy protection on Monday with a buyout offer in hand from a private equity firm, the latest twist in its efforts to survive the sexual misconduct scandal that brought down co-founder Harvey Weinstein, shook Hollywood and triggered a movement that spread out to convulse other industries.
The company also announced it was releasing any victims of or witnesses to Weinstein's alleged misconduct from non-disclosure agreements preventing them from speaking out. That step had long been sought by New York Attorney General Eric Schneiderman, who filed a lawsuit against the company last month on behalf of its employees.

The Supreme Court seems likely to strike down a California law that mainly regulates anti-abortion crisis pregnancy centers.
Both conservative and liberal justices voiced skepticism Tuesday about the law that requires the centers to tell clients about the availability of contraception, abortion and pre-natal care, at little or no cost. Centers that are unlicensed also must post a sign that says so.
The centers say they are being singled out and forced to deliver a message with which they disagree. California says the law is needed to let poor women know all their options.
Similar laws also are being challenged in Hawaii and Illinois.

Facebook Chief Information Security Officer Alex Stamos is reportedly leaving after disagreements over how the social media network should handle the spread of disinformation, the New York Times reported.
In a tweet, Stamos said he was still employed, but that his role had changed to "exploring emerging security risks and working on election security."

At 32 years old, Saudi Crown Prince Mohammed bin Salman controls a vast fortune, a well-heeled military and the future of a nation in the throes of sweeping economic and social change. His ambitious bid to remake Saudi Arabia received a ringing endorsement Tuesday from President Donald Trump as the future leader opened a marathon tour of the United States.
Soaking in Trump's plaudits in the Oval Office, Prince Mohammed said little and left most of the talking to his host, who offered an optimistic forecast of lucrative U.S. arms sales to the kingdom and more Saudi investment in the United States.
