Surveillance footage exclusively obtained by DailyMail.com shows one of President Obama’s senior officials following a woman around a DC Metro station and taking a picture up her skirt with his cell phone.

William Mendoza was caught on security cameras carrying out the vile act while he was executive director of the White House Initiative on American Indian and Alaska Native Education.

As a result of his actions, the married father pleaded guilty to attempted voyeurism and resigned from his $140,000-a-year Department of Education post in Obama’s White House.

His arrest and conviction were never made public until DailyMail.com acquired the report of the investigation and the footage through a Freedom of Information Act request.

The video footage taken on July 5, 2016, contains five segments, put together as part of the Metro Police Transit Department (WMATA) investigation into Mendoza’s conduct.

The parts of the video are not in chronological order.

The first clip shows Mendoza following the woman wearing a jean skirt across the ticket hall and onto the escalator at the Union Station Metro with his cell phone in his hand.

The second shows him closely trailing the same woman along the platform after disembarking a train.

The third shows Mendoza waiting at the turnstiles and entering the ticketed area at the same time as the woman.

The fourth shows him walking across the ticket hall, taking his phone out of his pocket and turning it on.

In the far left of the shot you can see him getting closer to the woman on the escalator, bending down and the light on his cell phone turning on.

You can then see the flash from the camera as he takes the photo.

In the final part of the video you can see Mendoza following the woman on the platform from another angle.

Mendoza was arrested and charged in November 2016 after the woman, as well as three others, complained about his behavior cops.

He pleaded guilty to a charge of attempted voyeurism in January 2017, was given suspended 90-day prison sentence, one year’s probation and was fined $100. He has not worked in public office since stepping down.

DailyMail.com contacted his lawyer Paul Kiyonaga for comment, but he did not respond.

In a previous story about Mendoza's conduct, Kiyonaga told DailyMail.com that the he received treatment after his conviction and is now trying to move on with his life away from public office.

He said: ‘Mr. Mendoza has taken responsibility for this charge of attempted voyeurism.

‘He’s received treatment for the underlying issues that gave rise to this incident, and, with the strong support of his family, is moving forward productively with his life.’

According to Department of Education documents, Mendoza tried to take photos and videos up women's skirts at least four times on his government-issued iPhones in July 2016 without their consent.

He was also allegedly caught looking at footage, apparently filmed in secret, of a woman in her underwear getting changed in a dressing room. It is not known if he recorded the video himself.

When he took the indecent photos, he was supposed to be at work and was using a travel card funded by the taxpayer, according to the documents obtained by DailyMail.com through a Freedom of Information Act request.

Mendoza resigned just before the Department of Education could launch their own investigation into his sexual misconduct.

Mendoza became the executive director of the White House Initiative on American Indian and Alaska Native Education in December 2011, when President Obama created it by executive order.

Throughout his tenure working for the Obama Administration, Mendoza tried to get Native Americans get better access to education and also rallied against the use of tribal mascots in sports.

Mendoza worked under Education Secretary Arne Duncan and his successor John King.

He has at least three children, is part of the Oglala-Sicangu Lakota tribe and is a fixture of the protests against the Dakota Access oil pipeline with his wife, Heather.

The documents obtained by DailyMail.com say Mendoza took four of the upskirt photos on subway trains in the capital and was caught on a platform watching a video of a woman in her underwear in a dressing room.

Twice on July 5, 2016, between 2.00pm and 3.00pm, Mendoza used his cell phone to take two indecent pictures of women ‘in close proximity to their bottom’ at the Union Station Metro in the space of just 20 minutes.

One of the victims was wearing a ‘short jeans skirt’, as seen in the surveillance video, and the other had ‘extremely short cut black shorts’, according to police.

On July 7, 2016, at 8.23am a witness saw Mendoza behind a woman at the McPherson Square Metro station.

The victim was seen pulling her dress closer to her legs to cover up when she noticed the illuminated light of the cell phone, the documents state.

Police say he ran out of the train station after someone noticed his surreptitious actions while a bystander shouted ‘stop’.

A detective called her about the incident during investigation, and said that a man who looked like Mendoza also tried to take a photo up her skirt on a subway train two weeks earlier.

Later on July 7, at 6.19pm, Mendoza was caught on a surveillance camera taking out his phone and looking at a video showing a woman’s underwear underneath a white dress.

The report states the footage ‘appeared to have been surreptitiously filmed in a store’s dressing room.

On July 8, at 9.25am, Mendoza left one of the platforms at the Farragut West Metro station and started following a woman wearing a maroon dress onto the escalators.

According to the documents he placed his cell phone ‘near the bottom of her dress’ while behind her and took the picture.

Just one minute later, he walked back down the stairs and waited in an unpaid area of the station.

He waited until he saw another woman wearing a blue dress. Mendoza stood behind her on the escalator, took another picture, and then walked away.

In August 2016, the Washington Metro Transit Area Authority Police Department (WMATA) contacted the Department of Education to say they were investigating Mendoza.

Part of the investigation was analyzing the security footage before it was obtained by DailyMail.com.

On November 25, 2016, before the Office of the Inspector General finished their probe into his conduct, he resigned.

Five days later, a detective from the WMATA got a search warrant for Mendoza's government-issued electronic items, including his laptop.

He pleaded guilty to one count of attempted voyeurism in the Superior Court of the District of Columbia on January 13, 2017, and was given a 90-day suspended prison sentence as part of a plea agreement.

Mendoza is seen left alongside former Education Secretary Arne Duncan at the Rosebud-Sioux Tribal Fair in 2011 where Obama met Native Americans. Mendoza resigned just before the Department of Education could launch their own investigation into his sexual misconduct and pleaded guilty to the charges in January 2017

Mendoza was also given one year probation and a $100 fine. After he pleaded guilty he sought treatment.

In April 2017, the Department of Education’s Office of the Inspector General advised he should be barred from federal employment ‘due to suitability’.

The voyeurism scandal wasn’t the only time Mendoza came under scrutiny for his conduct during his time in office.

An autistic man said he punched him and called him a ‘weetard’ for wearing a Washington Redskins sweater in 2015, a year before his run in with police.

Barrett Dahl, 28, says he was at a Native American gathering in Washington, DC in October 2015 when appointee Mendoza spotted him wearing the sweater.

'He comes to me and says you're a "weetard" for wearing a Redskins shirt,' Dahl told Oklahoma TV station KFOR at the time.

'He says where are you from that you're such a "weetard," you don't understand that you're offending me?'

Mendoza (pictured in 2016) pleaded guilty to a charge of attempted voyeurism in January 2017, was given suspended 90-day prison sentence, one year’s probation and was fined $100. He has not worked in public office since stepping down from Obama's administration

Mendoza told News9 that he politely asked about the words 'INJUN PIMP' on the back of Dahl's shirt, and that Dahl responded violently.

According to Mendoza,, Dahl said: 'I don't have to (expletive) explain (expletive) to you. If you want to step outside and take this outside, I'd be happy to explain it to you.'

Dahl says his shirt said 'INJUN PLAYER.'

Mendoza says he offered Dahl his hand after seeing him on the escalator and apologized for upsetting him, but Dahl then attacked.

'He was holding a cup in his hand,' Mendoza wrote, 'at which point, he threw its contents that was the smell of coffee and was hot, but not scalding.

'He then punched me in the face (right cheek). I tried to grab him but we both fell.'

Mendoza strenuously denied the allegation.

He was not arrested, and has never been accused of criminal wrongdoing in relation to the confrontation with Dahl.

The Department of Education confirmed to DailyMail.com that Mendoza resigned before the internal investigation into his conduct concluded.
