Input: Consider Input: CHRIS WALLACE  " FOX NEWS SUNDAY" HOST: I'm  Chris Wallace .
 WALLACE : Partisan finger-pointing and uncertainty after a standoff in the Senate over immigration. We'll discuss the fallout for Americans and who will get the blame with White House Budget Director Mick Mulvaney and Democratic Senator Chris Coons  part of a bipartisan group trying to work out a compromise.
 WALLACE : We'll ask our Sunday panel about the Trump presidency one year after his inauguration.
 WALLACE : All right now on "Fox News Sunday."
 WALLACE : Not good if they are arguing over posters.
 WALLACE : Describe the extent of the shutdown both in terms of personnel and programs.
 WALLACE : You are calling this -- we heard it  saw it in the open  the Schumer shutdown. But the fact is you only have 46 Republicans willing to vote for this congressional  this continuing resolution. So  even if there hadn't been a Democratic filibuster  you didn't have the majority needed to pass the C.R. All the more reason  isn't this on Republicans and the White House and control of the House and the Senate?
 WALLACE : It's not just because of Democrats.
 WALLACE : The point is  you do not have your own house in order. You only have 46 Republicans supporting this.
 WALLACE : But you only had 46 Republicans.
 WALLACE : Well  you don't have 46 Republicans either. I mean  you don't have 51 Republicans either.
 WALLACE : Back in 2013  when Republicans insisted on shutting down the government because they wanted to remove all funding of ObamaCare and they did it for 16 days  private citizen Trump placed the responsibility squarely. Here he is.
 WALLACE : But why doesn't he -- I mean  he didn't have a meeting  a bipartisan meeting with congressional meetings yesterday. Does he have one on the schedule for today?
 WALLACE : You blame Democrats for holding the government hostage now  but back in 2013  you supported holding the government hostage on this question of ObamaCare. Take a look.
 CHRIS WALLACE   FOX NEWS HOST: Why was that legitimate then  the right reason to have a fight  but it's not legitimate now?
 WALLACE : I wasn't saying a word.

Input: Consider Input: "2017 was a strong year for Facebook  but it was also a hard one " Facebook founder and  CEO Mark Zuckerberg  said in a statement. "In 2018  we're focused on making sure Facebook isn't just fun to use  but also good for people's well-being and for society. We're doing this by encouraging meaningful connections between people rather than passive consumption of content."
 Zuckerberg  noted that the company's recent news feed changes  such as reducing the volume of viral videos  have caused time spent on Facebook to decline by about 50 million hours every day - an average of about 2 minutes per person every day.
On a conference call with investors   Zuckerberg  emphasized that time spent alone offers limited insight into the value of the social network and that  he  expects short-term drops in time on the site to make the product stronger in the long-term.
"By focusing on meaningful interactions  I believe that the time spent on Facebook will be more valuable "  Zuckerberg  said. "If people interact more  it should lead to stronger community. When you care about something  you’re willing to see ads to experience it."
Facebook’s results come just a few weeks after  Zuckerberg  announced that  the company  plans to make a year-long shift across  its  products to prioritize interactions between friends and family and reduce the prominence of unpaid posts by brands and publishers. In the near-term  the change will cause news to make up only 4% of news feed  down from about 5% currently. Facebook plans to display news sources in accordance with how users rank their “trustworthiness.”  Zuckerberg  also said  the company  plans to elevate local news in a push to help “build community.” Facebook correctly warned that the changes could lead to a decrease in time spent on the social network in the short-term. However   Zuckerberg  has said  he  sees the shift as critical to Facebook’s long-term success as a business and product.
When Facebook reported its third quarterly earnings in November   Zuckerberg  said  he  was “dead serious” about addressing the social network’s security and safety issues  ranging from election meddling to moderation issues  such as violent live videos and misinformation.  Zuckerberg  warned that the bolstered efforts “will impact” the company’s profitability.  The company  said last year  it  plans to double  its  headcount working on safety and security from 10 000 people to 20 000 people over the course of 2018  and add thousands more content moderators. (Facebook said it has 25 105 employees as of December 31  up 47% from a year earlier.)
Zuckerberg continues to emphasize video advertising as key to the future of the company’s business. Facebook recently added a “Watch” section for video shows and series  which competes with Google-owned YouTube and is intended in the long-term to foster interaction between friends  family and groups. Higher-quality content in the tab could drive stronger video ad sales over time.  Zuckerberg  also noted in Wednesday's conference call that  he  expects "Stories" -- chains of disappearing photos and videos -- to overtake posts and feeds as the most common content format across apps  and that the growth of the feature will shape how Facebook evolves its apps and business.
