Aly Raisman reclaimed her power and eviscerated her abuser Larry Nassar as she stared down the pedophile doctor and delivered a remarkable impact statement on Friday.

The six-time Olympic medalist turned heads earlier in the day when she made a surprise appearance at the Michigan court where Nassar is being sentenced, just before the hearing was to start.

She entered the courtroom with another surprise guest, fellow Fierce Five teammate Jordyn Wieber, who grew up in the area and was just 8 when she began working with Nassar.

Wieber would be the first to speak, revealing publicly for the very first time that she too was sexually assaulted by Nassar.

'I'm a victim of Larry Nassar,' stated an emotional but incredibly composed Wieber at the start of her statement.

Raisman made her remarks later in the day and delivered what was without question the most powerful speech of the week.

'I am here to face you, Larry, so you can see I've regained my strength,' said Raisman.

'That I am no longer a victim. I am a survivor.'

Raisman shed not a single tear and showed no sign of weakness as she spoke, looking right at Nassar the entire time.

'I didn't think I would be here today,' said Raisman, who had previously announced her statement would be read in court by a member of the district attorney's office.

'I was scared and nervous. It wasn't until I listened to the other brave survivors that I realized I needed to be here.'

She did not detail her abuse, and said only that Nassar's grooming began when the two were in Australia, and that she was eventually manipulated into believing that the doctor's 'inappropriate touch would heal my pain.'

I am here to face you Larry so you can see I've regained my strength. That I'm no longer a victim, I'm a survivor. I am no longer that little girl you met in Australia, where you first began grooming and manipulating. As for your letter yesterday, you are pathetic to think that anyone would have any sympathy for you. You think this is hard for you? Imagine how all of us feel. -Aly Raisman, 23

Raisman knows better now she said in her statement.

'You never healed me. You took advantage of our passions and our dreams,' said Raisman.

'Imagine feeling like you have no power, and no voice. Well you know what Larry, I have my power and my voice,and I will use them.'

Raisman also used her time in court to speak on behalf of all the victims in the case.

'The tables have turned, Larry. We are here. We have our voices, and we are not going anywhere, said Raisman.

'And now, Larry, it’s your turn to listen to me.'

Raisman proceeded to call Nassar 'pathetic,' among other things, for the letter he sent the judge earlier this week complaining about the toll these impact statements were taking on his mental health.

'You are pathetic to think that anyone would have any sympathy for you. You think this is hard for you? Imagine how all of us feel,' Raisman told Nassar.

When she had finished, Judge Rosemarie Aquilina shared a few words with the brave survivor.

'You were never the problem, but you are so much the solution,' said Judge Aquilina.

'You are unstoppable. You are part of an unstoppable growing force, an unstoppable, strong, loud voice. The effects of your voice are far-reaching. It's not just in this courtroom, but worldwide.'

Judge Aquilina then told Raisman: 'You're one of the strongest survivors I have ever seen.'

Raisman and Wieber spent the entire day in the courtroom, returning after lunch in a show of support for the other women who were sharing their stories that day.

It was Wieber who walked to the podium to start the day, revealing for the first time that she was one of the many young women who was sexually assaulted by Larry Nassar.

Wieber fought back tears as she addressed her abuser, who as he has done for the past few days hid his hands.

'I thought that training for the Olympics would be the hardest thing I would ever had to do,' said Wieber.

I thought that training for the Olympics would be the hardest thing I would ever had to do. But in fact, the hardest thing I ever had to do was process that I was a victim of Larry Nassar. -Jordyn Wieber, 22

'But in fact, the hardest thing I ever had to do was process that I was a victim of Larry Nassar.'

'It has caused me to feel shame and confusion,' said Wieber of her abuse when she took the podium at the start of the day.

'I have spent months trying to think back on my experience and wonder how I didn't know what was happening to me and how I became so brainwashed by Larry Nassar and everyone at USA Gymnastics. Both whom I thought were supposed to be on MY side.'

Wieber, as many women have done before her this week, noted that Nassar was not the only person who should be held accountable for these horrifying acts.

'Larry Nassar is accountable. USA Gymnastics is accountable. The U.S. Olympic Committee is accountable,' said Wieber.

'My teammates and friends have been through enough and now it's time for change. The current gymnasts should not have to live in anxiety and fear as I did.'

Wieber, 22, later told the court that her abuse began when she was 14, and went on for years, stating: 'He did it time after time, appointment after appointment.'

She later noted: 'The worst part is I had no idea he was sexually abusing me.'

Proud: 'Even though I'm a victim, I do not and will not live my life as one. I am an Olympian,' said Wieber

High price: 'I thought that training for the Olympics would be the hardest thing I would ever had to do,' said Wieber

Still going: Raisman seemed intent on making sure that Nassar saw her and the other victims in court

Wieber also said that she, Raisman and McKayla Maroney discussed the concerns they all had with Nassar's treatment, before revealing that all three kept quiet because they did not want to jeopardize their spot on the Olympic team.

'Was Larry even doing anything to help my pain? Was I getting the proper medical care? What was he thinking about when he massaged my sore muscles every day?' asked Wieber.

'Now, I question everything.'

Even at the pinnacle of her career has been tarnished because of Nassar, with Wieber revealing: 'Our bodies were all hanging by a thread in London. Who was the doctor that USAG sent? The doctor who was our abuser.'

This is all your fault, we wouldn't be here in the first place if it wasn't for you. You are a coward and a sickening man. You did this to me. You're the one causing all this pain I am a survivor. Here I am today, facing my abuser. I'm finally being heard. I'm no longer hiding my story. - Chelsea, 15

Wieber is working to move past her abuse she said, and is refusing to let what Nassar did to her define her life.

'Even though I'm a victim, I do not and will not live my life as one,' said Wieber.

'I am an Olympian.'

Wieber then made a point of stating that her Olympic title carries no weight in this trial.

'I want everyone, especially the media, to know that despite my athletic achievements, I am one of over 140 women and survivors whose story is important,' said Wieber.

'Our pain is all the same, and our stories are all important.

Wieber was followed by Chelsea , who is just 15, and started being abused by Nassar three years ago.

She appeared with her mother as she is a minor, and bravely delivered her tearful statement.

Chelsea said that she tore a muscle in her stomach when she was 12 and went to see Nassar, noting at one point how he told her to wear loose shorts so that he could have easier access to her body.

'It's so sickening that he did that to me,' said Chelsea.

Chelsea went on to call Nassar a 'monster,' and revealed that her love for gymnastics almost disappeared because of his abuse.

'This is all your fault, we wouldn't be here in the first place if it wasn't for you,' said the teenager.

'You are a coward and a sickening man. You did this to me. You're the one causing all this pain.'

She closed out her statement by saying: 'I am a survivor. Here I am today, facing my abuser. I'm finally being heard. I'm no longer hiding my story.'

She then asked Judge Aquilina that Nassar receive the maximum sentence.

Guilt: 'I was older, I should have known,' said Samantha Ursch (above), who admitted that she was focused on pretending that her assault was not real

Sisters: 'Today, I am a 15-year-old girl, and throughout my years in high school I've struggled. For the longest time, you deprived me of my happiness,' said Maddie (right with parents and sister Kara on left)

Samantha Ursch started out her statement by thanks Judge Aquilina for the support she has shown for each of the victims this week, which is the reason why so many have finally agreed to share their stories.

She was a senior at central Michigan University when she tore her ACL, but got the chance to possibly compote one more time in her final year of college when she managed to get an appointment with Nassar.

The first meeting went well, but the second happened after hours in his darkened office with no one present.

He was 'very invasive' said Ursch, who noted she called her mom afterwards becuase she 'felt dirty.'

You were never the problem, but you are so much the solution. You are unstoppable. You are part of an unstoppable growing force, an unstoppable, strong, loud voice. The effects of your voice are far-reaching. It's not just in this courtroom, but worldwide. You're one of the strongest survivors I have ever seen. -Judge Rosemarie Aqulina to Raisman

Her mother was concerned, but Ursh never said anything or reported Nassar, and she revealed on Friday that as a result she feels responsible for what happened to some of the victims.

'I was older, I should have known,' said Ursch, who admitted that she was focused on pretending that her assault was not real.

As for Nassar, Ursch stated: 'I hope he thinks about how he changed all of our lives. I'm not pretending I didn't happen anymore.'

Two sisters, Maddie and Kara, spoke next, with their parents having to give permission because both girls were minors.

Kara, who is 17, spoke about how she felt dirty after Nassar's treatments, revealing he used lubricant and a numbing cream while he molested her.

Her mother was in the room on one occasion, so Nassar strategically placed towels to obscure the woman's vision while he sexually assaulted her daughter.

The abuse stopped when Kara stopped seeing Nassar, but not the depression or suicidal thoughts or nightmares that she would raped in her sleep.

Her younger sister, who is just 15, comforted Kara at the podium while she spoke about her struggles.

'The first time I went to see Nassar, I was 12 years old. Being the little gymnast I was, I was beyond excited to have Nassar as my doctor,' said Madeline at the beginning of her statement.

An injury to her back had left her in constant pain, and rather than go to the hospital Madeline got an appointment with Nassar.

He told her that he was going to push down on her pubic bone the first time he molested her Madeline said, obscuring the act from her mother by blocking her view with his body.

When Maddie's father went to the appointments, 'the procedure' was not done by Nassar.

She was 12 at the time, and one of the last girls to be molested by Nassar.

When she learned about his crimes, just a few months later, Maddie said that she tried to convince herself she was not a victim.

'Today, I am a 15-year-old girl, and throughout my years in high school I've struggled,' said Maddie.

'For the longest time, you deprived me of my happiness.'

Brave: Anya Gillengarten was abused by Nassar when she was 16, and worried about coming forward because she is an employee at Michigan State University

Anya Gillengarten was treated by Nassar when she was 16, shortly after the gymnast was in a automobile accident.

She is now 33, and struggled with coming forward and speaking out on Friday because she is an employee at Michigan State University.

'My name is Anya. I am not a number,' she said to start her statement.

She has never been to see a doctor she revealed since she was abused by Nassar at his office, despite suffering from a number of medical conditions.

'People keep telling me I need to smile, as apparently I always have a scowl on my face,' she said in court.

That scowl comes after years pof depression and fear amd suicidal thoughts, all thre result of Nassar's abuse.

'Larry stole my childhood, my innocence, my virginity and my self worth,' said Gillengarten.'

'I hated myself. I still do. I was in a spiral of depression.'

A number of victims have criticized Michigan State University these past four days.

The school was Nassar's employer until September 2016, and failed to report a number of concerns about Nassar to authorities.

The university's board of trustees acknowledged that criticism Friday, asking Michigan Attorney General Bill Schuette to conduct an outside review of its actions.

'We are making this request because we believe your review may be needed to answer the public's questions concerning MSU's handling of the Nassar situation,' the trustees said in a letter to Schuette.

'These questions grew louder this week with the victim impact statements.'

Victims: Nassar abused at least four members of the Fierce Five (l to r: Raisman, Maroney, Douglas and Wieber with their all-around team Gold in 2012)

Wieber's decision to come forward was applauded by Judge Rosemarie Aquilina, who for the fourth straight day continued to address each victim after they spoke in court.

She told the young woman that despite her wish to play down her fame, what she did in court on Friday would inspire countless other young girls and women.

Wieber is retired from competitive gymnastics and now coaches the team at UCLA, where one of her athletes is fellow Fierce Five member Kyla Ross.

Larry stole my childhood, my innocence, my virginity and my self worth. I hated myself. I still do. I was in a spiral of depression. -Anya Gillengarten, 33

She is now the fourth member of the five-person London squad to reveal she was assaulted by Nassar, following Maroney, Raisman and Gabby Douglas.

Maroney had her impact statement read in court on Thursday and Raisman is expected to deliver her thoughts on Nassar later in the day on Friday.

Simone Biles, a member of the 2016 Rio team, also came forward to reveal she was one of Nasar's victims earlier this week.

Maroney revealed in a lawsuit filed last month that she received $1.25 million from the organization in December 2016.

The two-time world-champion vaulter agreed to sign a non-disclosure agreement as part of the deal, which imposes a $100,000 fine should she ever speak about Nassar or the abuse she suffered at the heads of the disgraced doctor.

Maroney, who was represented by Gloria Allred when she accepted that settlement, said that she was in desperate need of the money due to her deteriorating psychological state and need for treatment as a result of the abuse she suffered at the hands of Nassar.

She said at one point she was even thought about taking her own life.

Maroney is now suing USA Gymnastics - with her legal team arguing that it was illegal for the organization to have her sign a clause demanding her silence about her molestation.
