Obama will meet with House and Senate Democrats to discuss strategies to save his health reforms, which include focusing on aspects that have bipartisan support and exposing Republican divisions. Meanwhile, Pence will meet the many members of the majority Republican congress who are eager to repeal Obamacare. It brought health insurance to 22 million people and, for the first time in US history, means that more than 90% of Americans are insured. Barack Obama and Mike Pence slated for US healthcare showdown North Carolina officer slams student to ground A North Carolina officer has been filmed body-slamming a high school student. In a video spread widely on Twitter on Tuesday, the school resource officer at Rolesville high lifts the student up and slams her against the ground, causing a thud and a gasp from students. It remains unclear what the cause of the incident was. The News and Observer identified the officer as Ruben De Los Santos and reported that he was on paid administrative leave. The American Civil Liberties Union of North Carolina said it was investigating the issue and that it was considering a lawsuit. "This use of force is very disturbing and is never justified, especially in schools where kids are supposed to go to learn and be safe and to concentrate on their school work," said staff attorney Irena Como. North Carolina officer caught on video slamming female student to ground China critic picked as Trump trade chief Longtime China critic and protectionist Robert Lighthizer, 69, has been selected as Donald Trump's trade chief. The move indicates Trump intends to follow through on the tough stance he has threatened to take to against China; Lighthizer has often advocated increasing tariffs and called for the use of harsher methods against China. Beijing has already expressed deep concern about Trump's actions as president-elect, including his threat to use the sensitive issue of relations with Taiwan as a bargaining chip in a trade deal. Lighthizer will also likely work alongside Peter Navarro, who will lead the presidential office for US trade and industrial policy. Navarro has previously described China's government as a "despicable, parasitic, brutal, brass-knuckled, crass, callous, amoral, ruthless and totally totalitarian imperialist power".

Mark Zuckerberg sparked speculation that he may be considering stepping into the political arena after the Facebook chief announced he was planning to visit all the states he has not yet been to in 2017. "After a tumultuous last year, my hope for this challenge is to get out and talk to more people about how they're living, working and thinking about the future," he said in a Facebook post announcing the challenge. Theories of his potential public service began to swirl when court documents from a class action lawsuit in early December revealed two of the company's investors discussing how he could pursue a political career while remaining as CEO. Mark Zuckerberg's 2017 plan to visit all US states hints at political ambitions Senators aim to move US embassy to Jerusalem Three Republican senators – Ted Cruz of Texas, Dean Heller of Nevada and Marco Rubio of Florida – have introduced legislation to recognize Jerusalem as Israel's capital and move the US embassy there, which would fulfill one of Trump's campaign promises. After being sworn in, the three Republican senators introduced the Jerusalem Embassy and Recognition Act, which is similar to bills presented by Republican senators in the past that have not been successful. The US embassy has been located in Tel Aviv for half a century, as the state department has maintained a policy that the status of Jerusalem will be decided in peace talks between Israelis and Palestinians. Critics warn that the move could unleash a wave a violence. Meanwhile, one of Israel's most polarizing cases concluded on Wednesday with Israeli soldier, Sgt Elor Azaria found guilty of manslaughter for the killing Abdel Fattah al-Sharif, in Hebron in the West Bank last March. Republican senators introduce bill to move US embassy in Israel to Jerusalem Populism is not the answer Al From, the founder of the centrist Democratic Leadership Council, calls on Democrats to rededicate themselves to third-way politics, and reject the notion that a Bernie Sanders or Elizabeth Warren-type figure can save the Democratic party. "Democrats should rededicate ourselves to the core New Democrat principles – opportunity, responsibility, community," he writes. Don't be fooled. Populism won't help Democrats win again Serena Williams suffers shock loss Serena Williams crashed out of the Australian open in the second round after suffering a shock defeat to American Madison Brengle in three sets 6-4, 6-7 (3-7), 6-4. Eighty-eight unforced errors by Williams helped make her loss in the tournament, her first since losing in the US Open semi-final.

Speaker of the house Paul Ryan thought Congressman's Roger Marshall's son, Cal, was sneezing when the teenager tucked his head into his bent arm during a photo-op. He was in fact dabbing: a viral dance move popularised by US athletes and rappers, and embraced by teenagers as an irreverent or celebratory gesture.
