Arielle: Hey guys, I am Arielle Hixson, and let’s get started for this, the last day of January. First up, President Trump delivered on another of his campaign promises: to get rid of some rules on businesses.

President Trump campaigned to reduce federal business regulations. He says there are too many rules that hurt American businesses. So yesterday, the president signed an order being described as a "two out, one in” approach.

President Donald Trump: We have to knock out two regulations for every new regulation. So if there's a new regulation, they have to knock out two.

Arielle: Now, the latest move comes as companies criticize the president's U.S. travel ban on immigration from seven countries.Max Levchin is an immigrant from Ukraine and cofounded PayPal. He is worried about recruiting top talent from other countries.

Max Levchin: I think most people are frustrated, scared, angry. If America loses the status, the ability to attract the very best talent, I think we stand to lose a lot more than we stand to gain.

Arielle: And his thoughts were echoed across the high-tech industry. The CEO of Netflix called the ban “un-American.” Apple's CEO said,“It's not a policy we support.”

But as it stands now, the order’s impact might be limited. In 2013 nearly 274,000 skilled worker visas were issued in the U.S., but only one half of 1 percent of those were issued to citizens from the seven banned countries.Still, some companies are concerned about their global workforce.

But the White House defended the ban, citing national security reasons.

Sean Spicer: The president is going to be very proactive with protecting this country. We are not going to wait until we get attacked and figure out how we can make sure it doesn't happen again. He’s going to do everything in his power to stop every threat that we face in this country and every potential threat.

Arielle: But just hours after that comment from the White House, the acting attorney general, Sally Yates — an Obama appointee — ordered the Justice Department not to defend President Trump’s immigration order, writing she is not convinced the order is lawful. Jeff Sessions, who is expected to be confirmed as President Trump’s attorney general today, can easily reverse the decision.

And President Trump yesterday made a phone call to Canada's prime minister to offer his condolences for what is being called a terrorist attack on Muslims.

Gunfire erupted in this mosque in Quebec City Sunday night during evening prayers.More than 50 people were inside at the time; six were killed. Police arrested the man believed to be the shooter.

Prime Minister Justin Trudeau condemned the attack.

Prime Minister Justin Trudeau: This was a group of innocents targeted for practicing their faith.Make no mistake — this was a terrorist attack.

Arielle: Local officials had words of support for the community.

Quebec Premier Philippe Couillard: Muslim Quebecers, we are with you. This is your home. You are welcome here; we are all Quebecers.

Arielle: All right, coming up, why some stores you might shop at are singing "Closing Time."

Arielle: So if you have been out and about clothes shopping lately, here is a sign you might have seen.These days,there are plenty of them around as a lot of big-name brands are selling off their merchandise and shutting down. Emily Reppert tells us why.

Emily: It all started with the nation's largest department store, Macy's. The company recently announced it will close 100 stores and cut 10,000 jobs. One reason why: Experts say it is because it hasn't changed its business enough to catch up with the way people shop now — online.

Melissa Gonzalez: They’renot as nimble;they can’t change as quickly.They are not “technology first” companies, and so they are starting to reevaluate and restructure, and some going out of business, but they need to deliver something different to consumers now.

Emily: And it is not just Macy's; several other companies are closing their doors for good. The Limited is shutting all 250 of its stores, meaning about 4,000 people will lose their jobs.

Sears Holdings is shutting down more than 100Kmart and Sears stores. Office Depot — 450. And a dozen more like Aeropostale, American Eagle and Children's Place all have announced more than 100 storeswill close by the end of 2017.

This American Apparel store is going too. The company known for manufacturing most of its clothes in the U.S. has filed bankruptcy for the second time in just over a year and will close all of its stores across the country within the next few months as more people shop online and young people are buying more stuff at chains like H&M and Zara, which offer trendy clothes for a cheaper price.

The retail industry in total saw a nearly 3-percent increase in sales this past holiday season, but online shopping was the clear winner — up 17 percent from the year before.

Gonzalez: At the end of the day, you and I can hit a “buy” button from anywhere. So they all have to get savvier about how they create a stronger relationship with me, so when it's time for me to buy that mattress or to buy those shoes,I’m gonna think of that brand.

Emily: Emily Reppert, Channel One News.

Arielle: Tough times. Thanks,Emily.

Okay, next up, we take a peek at a career that puts athletes back in the game.

Arielle: Okay, today we take an inside look into what it takes to get your body back in shape after an injury. Whether you are someone who got into an accident, sprained an ankle or a top athlete sidelined due to an injury, a physical therapist can help you out. Scott Evans takes a look at a career that may be what is next for you.

Scott: Today, we are going to see what it is like to live a day in the life of a physical therapist, and Gary is one of the best in the business, so it was only right to spend it here. So, man, let's see where I am goingto be working today, huh?

GaryGuerriero:Let's go.Let's have some fun.

Scott: All right, let's do it.

When you walk in here, it kind of looks like a gym.Is that on purpose, or what?

Guerriero:It's totally on purpose.It’s set up like an athletic training room.

Scott: So what is the difference between,I guess,physical therapy and a trainer?

Guerriero:Physical therapy is more on the medical side of the field. There's different kind of specialties.Right now, we're in an orthopedic sports setting; there's cardiopulmonary; there's working with the elderly; there's pediatrics.

So,Scott, you ready to get going?

Scott: I mean,I am as ready as I will ever be.

Guerriero:Good.

Scott: So what is first?

Guerriero:I think we should probably start with some push-ups, get the upper body going a little bit.

Scott: I knew you were going to say push-ups first.I knew you were going to do that to me.

Guerriero:So let's get down, and feet together, hips up, so everything's like a table, straight across.

Scott: What made you decide you wanted to be a physical therapist?

Guerriero:Time I was young,I played sports, loved sports, and then, as I got into high school, had some injuries and knew I couldn't continue. I had a trainer who was amazing, and he really got me motivated into it. And that's where it started, so kind of junior in high school.

Scott: I think we have warmed up;we have gotten our whole fitness on for today.Let's see some physical therapy.

Guerriero:Okay, let's go.

Scott: All right, so what is happening now, man? Wow, okay.

Guerriero:This is Luke.

Scott: This looks intense.

Guerriero:He had a fractured dislocation in his ankle, playing rugby, so we're trying to get him back to the field.

Luke: It's been 11 months now, and I'm still not running.

Scott: Really?

Luke: Yeah.

Guerriero:So what we're trying to do is just elongate it, so it kind of comes back to its normal length, and then start to strengthen it.

Scott: Now, how painful is this experience for you?

Luke: Keep an eye on my face in about two minutes’ time, and you'll see.

Scott: Oh yeah?

Ah, there's his smile again.There’s that smile. He is like,“It's over.”

Guerriero:This is Clinton. He's gonna put a little electric stim on him.

Scott: Electric?

Guerriero:Electric stimulation.

Scott: He is about to shock you.

So we are talking about cutting-edge technology.

Guerriero:We try and mix things up based on the different situations that come up. Things are changing all the time, and it's just about trying to stay up on things and staying fresh.

Scott: So what is going on now?

Guerriero:Well, she had cartilage replacement in her ankle.

Woman: So they actually took it from a cadaver and did an ankle replacement.

Scott: Is that normal?

Guerriero:He's got a little grind in there.And if — here, give me your hands. Just put your hands on the same way. Just gonna — you feel a little bit of that grindin there?

Scott: Yeah. It’s like gravel.

Guerriero:It's a little what we call crepitus.Yeah, that's the technical term.

Scott: Crepitus — that's what that is.

Guerriero: Right, right.

Scott: Crepitus.

Guerriero: Crepitus.

Scott: Sorry, bro.

Gary,I have to say thank you for letting me shadow you for a day.Spending a day in the life of a physical therapist, man — it was pretty intense.I saw some things I didn't think I would see. So thank you, man.

Guerriero:Well, it was great having you, and I'm glad you learned a few things.

Scott: Indeed, indeed.

Arielle: Okay, so what is next if you want to become a physical therapist? Physical therapists need at least a bachelor’s degree, along with a doctor of physical therapy degree, which is another three years of school. Most physical therapists make about $84,000 a year. And we have got more healthcare careers up at ChannelOne.com, so take a look.

All right, guys, we have run out of time, but we will catch you right back here tomorrow.
