Protesters greeted Melania Trump at a migrant facility in Phoenix during her border tour, with a giant balloon-like figure that resembled President Donald Trump towering over the people gathered.

The hecklers were waiting for the first lady outside the Southwest Key migrant facility.

There were several dozen people with signs that read, 'End All Cages. Free the Parents and Children.' Some called for President Trump to be impeached. Others had obscenities on them.

As the first lady's motorcade left, the protesters attempted to chase it on foot but was held back by police.

Melania Trump's itinerary was kept under wraps until the first lady arrived at each of her stops. She started her day in Tucson before moving on to Phoenix.

Her communications director, Stephanie Grisham, explained that, having worked in Arizona politics, she knows how quickly protests can form and there's a special sensitivity for White House officials after recent events.

Several administration officials have faced public protests over President Trump's 'zero tolerance' immigration policy.

The first lady is in Arizona, for a visit to the southern border of the United States - but this time without her controversial jacket.

Her spokesperson also said Melania Trump was informed of the newspaper shooting in Maryland and wished to send her thoughts and prayers to all those affected.

Her second trip to the border wasn't overshadowed by her fashion choices like her first trip to Texas last week was.

The first lady wore a black shirt and white slacks for the flight.

She was not wearing her green $39 Zara jacket and it's slogan on the back: 'I really don't care, do u' that caught the internet's attention lat week.

At the Southwest Key migrant facility in Phoenix, Alexia Rodriguez, Southwest Key vice-president, welcomed the first lady, who greeted all in attendance warmly.

'We have been around for 20 years and this is a licensed child-care facility,' Rodriguez said. 'The primary work we do here is to try to do a safe reunification.'

The first lady said: 'It's great to be here and I wanted to come here last week. I was in Texas and I saw the facility where children are. So I wanted to come here and see your facility and meet the children. I want to thank all of you … Let me know what I can do to help you.'

Behind the facility was a playground, a large yard, a pool and a basketball court.

Inside what appeared to be a classroom, teaching material about the solar system hung on the walls, as well as number charts and alphabet charts. On another wall, hung posters about 'Plant Science.'

Vibrant paintings hung on the wall. One included words in English and Spanish, including 'DIVERSIDAD' AND 'familia.'

The first lady visited three rooms at the shelter.

The first room had four little girls and six boys. The walls were painted purple and blue and a video camera was hung on the wall.

The children each had a white piece of paper and were working on a construction project with rectangles, circles and squares that would ultimately make a green, red and yellow dog.

A plush elephant sat on one shelf on the wall. A plush monkey sat on another.

Melania Trump greeted the children in Spanish: 'Hola! Hola! Hello! How are you? Como estas?'

They responded, 'Bien.'

She crouched down to look them in the eyes asked what they were doing and told them their projects were 'beautiful.'

The first lady asked the children about their ages.

'Who is five,' she asked.

Six hands shot up in the air.

'Which are princes,' she asked them?

Some hands went up.

'Which are princesses,' she asked.

Other hands went in the air and the kids giggled.

The first lady held up five fingers and asked one little girl, 'Are you five?'

The girl held up her hand and give the first lady a high five.

The first lady and girl then fist-bumped.

A staffer told the class, 'Ella es Mrs. Trump, la Primera Dama de Los Estados Unidos.'

The first lady asked a girl if she liked it at the shelter and if she was making friends.

The girl nodded.

The first lady asked the class who liked soccer.

Several said they did.

'Me, too,' she said smiling.

The campus also included a home for a tortoise, several plastic toddler-sized playsets.

Melania Trump asked the children questions, which had to be translated by their teacher.

'Do you like it here with some friends?' Mrs. Trump asked.

'Si,' said one little girl.

'Do you like to dance with some music?' Mrs. Trump asked.

The girl shook her head. 'They're honest,' her teacher said.

The second classroom wasn't really a classroom but a multi-use space that served as a lobby, kitchenette and play room. On the walls were posters with grievance procedures and program regulations. It smelled of cleaning products. The play area had toys, books and a turned-off television. Two empty infant high chairs were lined up on the wall by the waste receptacle, and on the other side was a phone booth with a sign above it: 'Direct Line / Linea Directa.' On an easel was written: 'Social Studies theme: USA Money / Coins' with a circle underneath.

There were 10 more children, maybe slightly older, learning in English. The first lady entered as the children sat at a table working on art. She pointed to a piece of artwork by a young girl in a pink shirt and pigtails.

'Beautiful!' Mrs. Trump said.

'Gracias,' the girl replied. 'Say 'gracias' en ingles,' the teacher said. 'Thank you,' the girl said.

The first lady spoke to the children and the teacher.

Finally, the infant room where the babies were sleeping.

A marker board on the wall read 'Headcount 6.28.2018: 9 little ones.' It listed their names and ages, ranging from six months to two years. Next to the children's names were the names of four mothers who were also in the room. They, too, were all juveniles. There were five other staffers in the room for a ratio of 1:1.

There were the usual trappings of a nursery: a baby swing, two bright yellow wooden rocking chairs. On an alphabet carpet the boys and girls in various stages of walking, toddled around. One gummed an alphabet block. Another stacked giant building blocks on each other. In a book center, one mom thumbed through a book while a child played next to her.

The room smelled like baby powder.

The wall was covered in Disney cartoon characters: Mickey Mouse, Minnie Mouse, Donald Duck, Goofy, Tigger and Winnie the Pooh. Toys included plastic dolls, rattlers a plastic kitchen and small plastic food toys. One boy was playing some kind of bowling game with a soft ball and pins.

The first lady walked in and a little girl zoomed toward her, but then ran right past Mrs. Trump and into the arms of a teacher.

'Nice to meet you,' Mrs. Trump laughed.

'Where are the moms?' she asked. One was pointed out to her. 'Where is your baby?' she asked the girl, who pointed out a boy who was 14 months old.

'Wow, so cute,' FLOTUS said.

The young mother said she had been at the shelter for 12 days.

Melania Trump asked if the moms go to school and was told they do. The first lady also asked if breastfeeding moms are able to feed their children. The staffer told her they can.

Outside on the campus were a small, shaded playground, a small swimming pool, a small dirt field with soccer goals, and a basketball court.

At her first stop earlier in the day in Tucson, Arizona, she visited a Customs and Border Patrol facility, where she held a roundtable discussion with Border Patrol, Immigration and Customs Enforcement, the U.S. Marshals Service and a local rancher.

'I want to thank you for all your hard work. I know how difficult and dangerous your daily jobs are,' Melania Trump told agents. 'I am here to support you and help any way I can.'

At the roundtable, Kevin McAleenan, Commissioner of U.S. Customs and Border Protection, told the first lady 1,600 people – including 539 in families – tried to enter the United States illegally on Wednesday.

Rodolfo Karisch, Chief Patrol Agent of the Tucson Sector Border Patrol said immigration enforcement has been characterized as 'cruel and heartless, but that is not the case.'

'There's been a lot of misinformation put out to the general public about our facilities,' Karsich said.

He showed the first lady a photo of a six-year-old boy crossing the desert with a coke bottle and a note.

'People also have to understand the danger of the desert, of the heat,' he said.

Joyce Silva, a Border Patrol Agent, told Mrs. Trump she has been a border patrol agent for more than 20 years.

'I love my job. As a mother, it hurts to see the children. They don't know what's going on,' she said.

She says her job is to get them to safety and give them food, water, and 'toys if they want them.' She's also given children her lunch in the field.

'Thank you so much for all that you do,' the first lady told her.

The first lady shook hands with several dozen officers who served in her motorcade — first Phoenix police and then Arizona state police.

After the roundtable, the first lady went to an adjacent building to get a tour of a short-term detention facility.

This part of the facility had eight holding rooms, each with a different label – 'Males,' 'Juveniles,' 'Families' and removable status signs marked 'Processed' or 'Unprocessed.' Some rooms also showed a maximum capacity, from 9 to 13 people. All the cell doors were open.

The first part of the first lady's tour was in an elevated command pod called 'The Bubble.' She later came out into the area with the detention cells.

The first cell was for families. There was a mother and a 3-year-old in that cell, called 'Family Unit 8,' and the boy repeatedly peeked out of the door.

The first lady smiled at him and said, 'Hi! How are you?' The little boy later turned and looked at all the cameras before returning to the cell. His mother appeared to be in her older teens.

Also there were 10 boys, ages 14 to 17. Six of them sat silently and expressionless on a metal bench and on toddler-sized chairs outside one of the detention cells, wearing blue wrist bands on their right hands. They were watching the movie 'Ferdinand,' which was on mute. Spanish-language captions flashed across the screen. They wore boots with all their laces removed.

The largest and probably oldest boy nervously shook his legs, but they were otherwise motionless and apparently unfazed by the appearance of the first lady. Above them were pictures from coloring books of a school bus, a sports car, an ambulance and a dog.

Nearby was a cart filled with apple juice boxes, peanut butter crackers, baby wipes, applesauce, and boxed toddler food. Underneath the cart were unopened take and toss sippy cups.

A Mylar blanket could be seen inside of one holding cell. Another contained packaged wet towels for migrants to clean up during their stay. A wooden shelf intended for inter-office memos was also used to hold diapers.

All of the detainees were from Guatemala or Honduras. Since this is a short-term holding and processing facility, all had been there less than 72 hours.

Melania Trump communications director Stephanie Grisham said the purpose of the trip is to hear what they were seeing at the border.

Grisham said the trip was planned a couple days after Melania Trump returned from Texas last week, where she was unable to visit a Department of Homeland Security Facility because of flooding.

She said the first lady is taking the trip with the president's encouragement.

'She wasn't able to visit a DHS facility, and she wants to learn from the people on the front lines at the border,' Grisham said.

The legal situation for immigrant children has also changed, Grisham said, 'and she's anxious to learn how they're implementing the new process. There was a court case that threw a wrench in the works.'

Grisham said the first lady continues to discuss the issue with the president, but did not elaborate.

'This is a complex issue. She recognizes that,' she said.

'She's learning that these people at HHS facilities are providing some outstanding care under difficult circumstances,' Grisham said. 'She's advocating for quality care for these children under difficult circumstances.'

Grisham said that the first lady has given her husband her views on controversial political issues throughout his presidency, but conceded that it's never been as public as with the issue of immigrant children.

'I would say this is very visible. She cares about children deeply,' Grisham said. 'She also believes in strong border laws and treating everybody equally.'

There are no other senior administration officials accompanying the first lady on the trip.

The visit comes a week after Melania Trump traveled to the border town of McAllen, Texas, to meet with officials there dealing with detained families. She also met with children at one of the facilities.

But that trip was overshadowed by a jacket the first lady wore to and from Texas that said on the back: 'I really don't care, do u?'

The first lady's spokeswoman said it was just a jacket, with no hidden message, but interest in her baffling fashion choice was a distraction from the first lady's trip.

Her husband, President Donald Trump, undercut the no-message message by tweeting that his wife was saying she really doesn't care about the 'fake news' media.

More than 2,300 children have been separated from their parents at the border in recent weeks and some were placed in government-contracted shelters hundreds of miles away from their parents.

The president last week signed an executive order to halt the separation of families at the border, at least for a few weeks, but the order did not address the reunification of families already separated.

President Trump acknowledged one of the reasons he signed the order is that Melania Trump and Ivanka Trump spoke to him about it.

A federal judge on Tuesday ordered that thousands of migrant children and parents be reunited within 30 days - and sooner if the youngster is under 5. The order poses logistical problems for the administration, and it was unclear how it would meet the deadline.
