>> We pledge our lasting support to this most special relationship.>> A special tension in the air Friday as the new leaders of the US and Britain, Donald Trump and Theresa May, met at the White House, trying to steady one of the world's bedrock alliances as nationalist movements sweep both sides of the Atlantic.
>> We affirmed our unshakable commitment to this alliance.>> White House correspondent, Jeff Mason.>> So the US and Britain have always had that, so called, special relationship. Those two words are very important, especially to the Brits. Both leaders seemed interested in having that relationship strengthened.>> May, the first foreign leader to meet Trump as president, with trade and Russia topping the agenda.
But Trump's first week side trips into allegations of voter fraud, feuds with Mexico and the media, and praise for the use of torture hanging in the air and complicating matters for May.>> For many people in Britain those sound like alarming beliefs.>> Trump using his first conference as President to try to dispel doubts about his readiness to lead the free world.
>> We have a great general who has just been appointed Secretary of Defence. He does not necessarily believe in torture. I don't necessarily agree, but I would tell you that he will override because I'm giving him that power.>> Trump also saying he had a one hour phone conversation with Mexican President Enrique Peña Nieto.
>> We had a very good call.>> And saying he hoped to forge a, quote, fantastic relationship with Russia. Which is accused of using hackers to interfere with the 2016 campaign, and declining to say whether he would lift sanctions. May saying the sanctions must stay in place. For May, it's all about Brexit.
The stunning referendum vote to leave the European Union that unexpectedly ushered her into office. And topping her list, hopes for a bilateral trade deal with the US to blunt the economic blow from a break with Europe.>> I'm convinced that a trade deal between the US and the UK is in the national interest of both countries.
>> Trump rode an anti-establishment wave into office, which included heavy criticism of the North Atlantic Treaty Organization.>> We're united in our recognition of NATO, as the bulwark of our collective defence.>> It'll be interesting to watch if they walk sort of arm-in-arm. Or if things like sanctions against Russia and the Ukraine issue will divide them despite this show of togetherness.
>> Trump making a grand gesture of restoring a bust of Winston Churchill to the Oval Office. But it will take more than that, and words at a news conference, to silence worries about Trump's plans as he steps onto the world's stage.
