It's clear that Facebook played a big role in mobilizing people to participate in the global Women's March in Jan. And now researchers have determined just how much of an impact the social network had. According to a study from researchers at the University of Maryland, almost 70 percent of people who attended the DC march heard about it on Facebook. Meanwhile, 61 percent from friends and family. "The take-home message here is clearly that Facebook matters more than friends and family to mobilization," said Dr. Dana R. Fisher, sociology professor and leader of the study. "Which is surprising and a really big deal."

Two top House Republicans asked the Inspector General to investigate leaks surrounding the ouster of former national security adviser Michael Flynn.

The request came in a letter from House Oversight Committee Chairman Jason Chaffetz (R-UT), and Judiciary Committee Chairman Bob Goodlatte (R-VA). "We request that your office begin an immediate investigation into whether classified information was mishandled here," the letter to the Inspector General read. Trump's administration has been beset by damaging leaks over its first month, including reports of Flynn's contact with the Russian ambassador to the US in December that ultimately led to his downfall. President Trump himself has decried such leaks as the "real scandal." Chairman Chaffetz has so far declined to investigate President Donald Trump's potential conflicts of interest or potential ties to Russia between himself or his aides.

Sean Spicer has barely moved into his office. Three weeks after the inauguration, the only things adorning the White House press secretary's shelves are a framed picture of himself at the podium, a book on Naval Special Warfare (he's in the Reserve), and a Super Soaker commemorating the infamous "Saturday Night Live" skit in which he, played by an enraged Melissa McCarthy, berated reporters while dousing them with soapy water. Just beyond these walls, in the briefing room and the restaurants and hotel bars frequented by the town's journalists and politicos, conclusions about Spicer's future have already been drawn. The prevailing wisdom is that the combative press secretary is not long for his office, destined to be thrown out in a matter of months or perhaps weeks for failing at what everyone describes as the hardest job in Washington: defending, and pleasing, President Donald J. Trump.

President Donald Trump's smartphone and tweets are now the subject of a Senate inquiry. Sens Tom Carper (D-DE) and Claire McCaskill (D-MO) sent a letter to the Secretary of Defense requesting answers on whether President Trump is using an encrypted smartphone in office, or an unsecured personal device. "The national security risks of compromising a smartphone used by a senior government official, such as the President of the United States, are considerable," the senators wrote in the letter. The letter cites multiple reports, which claim President Trump has continued to use his "old, unsecured Android phone." Many of the tweets posted from Trump's personal account, @RealDonaldTrump, since taking office are also marked as coming from "Twitter for Android."

Top White House adviser Kellyanne Conway has apologized for citing a fake "massacre" in support of Donald Trump's travel ban, in an interview on CNN in which she acknowledged that not all of the mainstream media can fairly be characterized as "fake news."

Tapper asked Conway about some of Trump's false claims, including his claim earlier Feb 7 that the murder rate was at the highest point in 47 years -- which is wrong. "Everyday there are these sprays of attack and sprays of falsehoods coming from the White House. It would be better if they were not coming from the White House, for me and for you," Tapper said, adding that it inhibits news organizations' ability to focus solely on policy. "Agreed, and let me just say it has to go both ways. I do, Jake, I sincerely don't see a lot of difference in coverage from when he was a candidate and when he became the Republican nominee, the president-elect and, indeed the President," Conway said. Conway also apologized for shaming the press for not covering the "Bowling Green Massacre," an incident which did not occur. "I regretted it tremendously," Conway said. "I felt really badly about that."

[Commentary] In turning one of the most consequential decisions of the presidency into a primetime television event, and doing so before publicly sorting out the details of his latest executive order, President Donald Trump is governing in the way a television executive might, making moves that have the effect of controlling the narrative and driving ratings.

It's a familiar play for President Trump: During his presidential campaign, he made controversial statements or scheduled rallies to distract attention from his opponents. As president, however, Trump's big swings haven't moved the news cycle quite as much as they once did. Every major news organization covered Trump's Supreme Court tweet, but normally an impending nomination announcement would dominate the news; on Jan 30, it barely registered amid the cacophony of headlines and analysis surrounding the travel ban. At the Jan 30 White House press briefing, the majority of questions focused on the ban. There were only two about the forthcoming Supreme Court nominee.

A spectre is haunting the West -- the spectre of cyberwar. It's now clear, according to American intelligence agencies, that the Russian government engaged in a campaign of hacking, email leaks and fake news in an attempt to undermine the American political process -- and steer the presidential election to Donald Trump. Russia has repeatedly denied the allegation.

But many are now asking: Are we at cyberwar? In the cybersecurity industry -- mostly made up of hackers and spies -- the conventional wisdom was that cyberwar is like physical war. It's only war when someone dies or something explodes. But what happened during the recent American election is forcing experts to revisit that idea. "'Nothing's blown up' is the old school way of thinking," said Dave Aitel, a former scientist at the National Security Agency. "But I don't have to blow something up to destroy your country. I just have to reduce trust in your national way of life."

While on the campaign trail, Donald Trump made it clear that he wanted to deport illegal immigrants. His stance on high-skilled immigration, on the other hand, was more opaque. The H-1B visa is the most common pathway for high-skilled foreigners to work in the US. Trump called it "very, very bad for workers" on the campaign trail and, after being elected, pledged to investigate visa programs that were abused. However, he also admitted that he's hired H-1B workers for his own businesses.

Uncertainty over what will happen under Trump has some foreign engineers thinking twice about working for a startup.

Some of the world's richest countries are very poorly served with mobile Internet. The US, UK, and Germany are still lagging behind developing nations when it comes to 4G access and download speeds. A report by consultancy OpenSignal found that American users have to put up with an average speed of just 13 Megabytes per second. That's the 69th slowest in the world, and way behind countries such as Ecuador (25 Mbps), China and Kazakhstan (both 22 Mbps). World leader Singapore boasts 46 Mbps. And the global average stands at 17.4.

While the US ranks poorly in speed, it's doing much better in terms of access. A typical user in the US can get onto a 4G network 81% of the time. That puts the US in 10th spot in the global ranking. The UK, by contrast, ranks just 54th in the world in terms of 4G availability. A typical user in Britain can only access 4G 58% of the time, behind Albania, Panama and Peru. Speed in the UK isn't all that great either, although with 21 Mbps it is still doing better than the US.
