  • CARL AZUZ: One chamber of the US Congress

  • has voted to overturn a presidential emergency

  • declaration.

  • I'm Carl Azuz with your down-the-middle explanation

  • of what that means.

  • When he was on the campaign trail in 2016,

  • future US president Donald Trump promised

  • to build a wall along America's southern border with Mexico.

  • He recently asked Congress for $5.7 billion to pay for it.

  • Congress did not approve that.

  • It set aside a little less than $1.4 billion

  • for border security.

  • So earlier this month, the president

  • declared a national emergency.

  • That would allow him to access the money to build a wall

  • or barrier without the approval of Congress,

  • even though Congress has the constitutional control over how

  • the government spends public money.

  • Presidents have been allowed to declare

  • national emergencies under a law that was passed in 1976.

  • And they've done that dozens of times.

  • But under that law, Congress also

  • has the authority to stop the emergency declaration.

  • And while it hasn't done that before, one chamber of it,

  • the House of Representatives, voted

  • yesterday to overturn President Trump's emergency declaration.

  • So what happens next?

  • Well, it's now up to the Senate to vote in the weeks ahead.

  • And we don't know how that'll turn out.

  • The house is controlled by Democrats who

  • mostly disapprove of the wall.

  • In the Senate, Republicans, who mostly support the wall,

  • have a small majority.

  • But some may still vote against the Republican president's

  • Emergency declaration because they're concerned

  • that a future Democratic president

  • can use the same power to do something they don't want.

  • Even if the Senate joins the house in overturning

  • the emergency declaration, President Trump

  • would veto that, and it would probably stand.

  • But there are other challenges.

  • 16 states have filed a lawsuit to block the declaration

  • from going through.

  • President Trump said he expected that and that the Supreme

  • Court would ultimately side with his administration.

  • How and when all this plays out is in the hands

  • of Congress and the courts.

  • Another priority for President Trump

  • is getting the communist nation of North Korea

  • to completely give up its nuclear program.

  • He's in the Southeast Asian country of Vietnam

  • right now for a second historic summit

  • with North Korea's leader.

  • Kim Jong-un is hoping that the US

  • will end its sanctions, its economic penalties,

  • on his country.

  • The question of which nation should make the first move

  • has been a sticking point since the two leaders first summit

  • last summer.

  • Ahead of their second meeting, the White House

  • said just the fact that these rival leaders were getting

  • together was a victory and that a third summit down the road

  • might be necessary for them to reach a final agreement.

  • But several international analysts

  • are saying that this summit is when action needs to be taken.

  • WILL RIPLEY: US President Donald Trump

  • and North Korean leader Kim Jong-un

  • are meeting for a second time.

  • First, it was Singapore-- now, Hanoi, Vietnam.

  • Whatever you want to call it, Trump-Kim,

  • Round Two, Trump-Kim, The Sequel, Trump-Kim 2.0,

  • it's surreal.

  • These guys went from trading threats--

  • DONALD TRUMP: They will be met with fire and fury.

  • WILL RIPLEY: --to exchanging letters.

  • DONALD TRUMP: And then we fell in love, OK?

  • No, really.

  • He wrote me beautiful letters.

  • WILL RIPLEY: But let's be real.

  • Analysts say it'll take much more

  • than letters for the Hanoi summit

  • to deliver what Singapore did not--

  • actual progress on denuclearization.

  • The first summit was heavy on symbolism, light on specifics.

  • Trump and Kim signed a vaguely worded agreement.

  • It allowed them to walk away with very different ideas

  • of what should happen next.

  • Now, you can argue both sides have

  • taken steps to reduce tensions.

  • Before the summit, Kim suspended missile

  • launches and nuclear tests.

  • The North Koreans even took us to their nuclear test sites

  • so we could watch them blow parts of it up.

  • After the summit, North Korea handed over a few dozen

  • sets of Korean War remains.

  • Trump suspended joint military exercises with South Korea.

  • He sent his top diplomat, Mike Pompeo, to Pyongyang

  • four times.

  • MIKE POMPEO: We had productive, good-faith negotiations.

  • WILL RIPLEY: But talks fell apart.

  • The US wanted North Korea to be transparent about its nuclear

  • program and to start taking irreversible steps

  • to get rid of nuclear weapons.

  • DONALD TRUMP: Complete denuclearization.

  • WILL RIPLEY: Did that happen?

  • No.

  • North Korea wanted the US to ease up

  • on sanctions pressure, work on building trust,

  • normalizing relations.

  • Did that happen?

  • No.

  • That's what makes the second summit in Hanoi so important.

  • Analysts say both sides need to come

  • to the table with realistic expectations, a willingness

  • to compromise, and they need to walk away with a specific plan.

  • Singapore delivered plenty of made-for-TV moments.

  • Hanoi needs to deliver results.

  • CARL AZUZ: 10-second trivia, which

  • of these airports sees more passengers than any other--

  • Hartsfield-Jackson Atlanta, Beijing Capital, London

  • Heathrow, or Chicago O'Hare?

  • With more than 100 million passengers annually,

  • Atlanta's Hartsfield-Jackson International is considered

  • the world's busiest airport.

  • And it's near that airport that a major US airline

  • has just opened a massive facility

  • where jet engines are tested.

  • Let's say a plane with two engines is in the air,

  • and one of them gives out.

  • The plane can still stay aloft.

  • But the thrust in the working engine

  • needs to be increased quickly to produce an extraordinary amount

  • of power.

  • And facilities like this one are built

  • to make sure the engines, with their tens of thousands

  • of parts, can handle that pressure

  • long before they're mounted on a plane and put in the air.

  • The future of testing some of the most powerful jet engines

  • in the world is right here at Delta's

  • brand-new facility in Atlanta.

  • MIKE MOORE: This is exciting because this is the largest

  • test cell in the world.

  • And we're going to be able to run engines 30, 40,

  • 50 years into the future because of the way

  • we've built this facility.

  • CARL AZUZ: The engines that keep travelers

  • up in the air during tens of thousands of flights a day

  • have to be checked regularly to make sure they're safe to fly.

  • That's what this place is for.

  • DON MITACEK: Well, airline engines

  • are getting bigger and bigger because we're

  • building bigger and bigger, more efficient wide-body aircraft.

  • MIKE MOORE: This test cell can handle

  • up to 150,000 pounds of thrust.

  • And when you think of thrust, just think

  • of as you stand on a scale.

  • Instead of standing on the scale,

  • you would hold the scale horizontally

  • and push it in space.

  • That's thrust.

  • CARL AZUZ: Everything in here is gigantic,

  • designed to keep the engines' massive power inside the cell

  • and away from bystanders.

  • The walls are made of concrete 3-feet thick,

  • and the doors weigh more than 300,000 pounds.

  • A huge lift is built into the floor

  • so workers can reach the engines, which

  • can weigh more than 8 tons.

  • MIKE MOORE: A typical engine when

  • it goes through the rebuild process is in a shop

  • anywhere from 60 to 90 days.

  • The engines are completely disassembled.

  • All the piece parts are inspected.

  • Everything's reassembled, and then it has to come

  • to this facility to be tested.

  • The testing allows us to make sure that oil, temperatures,

  • oil pressures, rotor speeds, exhaust gas temperatures,

  • thrust, everything meets the parameters that we know

  • that when we put it out on the aircraft

  • that it's going to last as long as it's supposed to.

  • DON MITACEK: We expect this facility

  • to support not only Delta Airlines but 150

  • other customers we have.

  • And that should equate to about 1,000,

  • 1,200 engines in the next three to five years.

  • The real story about this facility

  • is not that it's the largest test cell in the world,

  • but it's what it represents.

  • It's a legacy our senior technicians

  • are going to leave behind.

  • CARL AZUZ: It's all aimed at making Delta more

  • competitive as more and more airliners and passengers

  • take to the skies.

  • [GUITAR ROCK PLAYING]

  • Winning 10 out of 10 today, what could be the world's

  • most extreme model plane.

  • A Chinese farmer always dreamed of owning a passenger jet,

  • but they're expensive.

  • So he built his own.

  • This is a model of an Airbus A320.

  • It is life-sized.

  • It reportedly took more than 60 tons of steel to build,

  • and its materials cost the farmer almost $400,000.

  • Along with a team of a few other farmers turned mechanics,

  • they put this together in a little over two years.

  • (RAPPING) It's a dream of a model and a model of a dream.

  • Maybe it'll never catch an in-flight airstream.

  • But it's taken off in interest if not taken off the ground.

  • It's a soaring success even though it's earthbound.

  • It's a one-to-one scale reproduction fantasy.

  • Was it worth it?

  • Well, that's plain to see.

  • I'm Carl Azuz.
