She has been an actress for more than a decade, but it was a single Instagram post that put Louise Linton's name in national headlines.

The wife of Treasury Secretary Steve Mnuchin had posted a photo of herself disembarking from a military jet, tagging every item of her head-to-toe designer outfit.

Now Linton, 38, is set out to prove that she is a vegan environmentalist who believes in diversity and makes sure to hire transgender actors on her films.

It's a stark contrast to the Washington DC social circles in which Linton runs in, with friends including the president himself - who she says has a 'great sense of humor'.

Louise Linton, the wife of Secretary of the Treasury Steve Mnuchin (pictured together in May) is set out to prove that she is a vegan environmentalist who believes in diversity and makes sure to hire transgender actors on her films

As Trump's administration works to ban transgender people from the military and homeless shelters, Linton is celebrating her efforts to hire them.

The Scottish actress, who has appeared in Cabin Fever and CSI, is currently directing and starring in the film Me, You, and Madness.

In the movie she plays a bisexual psychopathic killer who is 'uninhibited' and 'very carnal and confident in her sexuality'.

Linton told the Sunday Times that she is proud of the diversity she brings to her film company Stormchaser.

'I made sure I cast a transgender actor, two African-American women, a gay guy and a gender-neutral person,' she said of her most recent film, which features both lesbian and heterosexual sex scenes.

'This was partly to represent who I am as a filmmaker and how I love diversity and inclusivity,' she added.

But the film also stars Ed Westwick, who was accused of rape by two women, and sexual assault by a third, at the height of the #MeToo movement in 2017.

'I don't believe that he did those things,' said Linton as she defended her co-star. 'I don't really believe in torpedoing someone's career when they've been absolved of doing something.'

Linton is also happy to defend the Trump family, who she counts among her friends.

The actress' 2017 wedding to Mnuchin, 58, was attended by Trump, Melania, Ivanka and Jared Kushner, and even officiated by Vice President Mike Pence.

Two months after her wedding to Mnuchin, Linton raised eyebrows when she posted a photo of herself walking off the military plane with him. She had tagged every designer in her outfit and got into a fight with a Portland mother-of-three in the comments, calling her 'out of touch'

The actress said she is still perplexed by the fact that she was mocked for wearing long black leather gloves while posing with Mnuchin and a sheet of dollar bills bearing his name

Linton calls Ivanka the 'most amazing mother' and often pays her visits when she's in Washington DC.

'I go over there with one of my dogs for the kids to play with,' she said. 'We're just two young women making our way in the world. We sit there in sweatpants and have a glass of wine.'

Linton also praised Melania, who she called 'sincere, warm, and humble'.

'It's impossible to fully relate with someone who's that glamorous and has all these different facets of her life, but I wish people could understand that these people are public figures but they're also mothers, daughters, and sisters,' she said.

'They're relatable, even if their lifestyle is so different. It so saddens me that people don't give other people the benefit of the doubt in the way they'd want to be given it.'

Like the Trump family, Linton is no stranger to controversy.

Two months after her wedding to Mnuchin, Linton raised eyebrows when she posted a photo of herself walking off the military plane with him following a trip to Kentucky.

'Great #daytrip to #Kentucky!' she wrote in the captions alongside the hashtags #rolandmouret, #hermesscarf, #tomford and #valentino to note the labels she was wearing.

The picture received swift backlash, including from Portland mother-of-three Jenni Miller, who commented: 'Glad we could pay for your little getaway. #deplorable.'

Linton replied to Miller's comment, calling her 'adorably out of touch' and sarcastically writing that her life 'looks cute'.

'Have you given more to the economy than me and my husband? Either as an individual earner in taxes OR in self sacrifice to your country?' she wrote.

Linton's Instagram is now scarce of glamorous outfit choices, instead showcasing her philanthropic work

'Pretty sure the amount we sacrifice per year is a lot more than you'd be willing to sacrifice if the choice was yours.'

Looking back, Linton - who has homes in Los Angeles, DC, and Manhattan - said she now 'completely' understands 'why people were outraged'.

But the actress said she is still perplexed by the fact that she was mocked for her outfit choice while posing with Mnuchin and a sheet of dollar bills bearing his name.

'Yes, I wore long, black leather gloves one day,' she said. 'Does that make me the DC [Comics] villain?'

While she may now be one of DC's power wives, it is still Los Angeles that Linton loves to call home.

'I like the creativity here,' she said. 'I like that people are liberal, open-minded, and progressive.'

Linton now has the help of a Washington 'protocol expert' to help prevent future scandals

It's a quality she's trying to pass down to Mnuchin, who she says is 'very habitual'.

'I'm adventurous, I like change,' she said. 'I like to try different food. Her's very habitual, doesn't like change, and doesn't like to try loads of different foods, but I always force him to.'

'And he's funnier than people would ever guess. He can be really playful and goofy.'

Linton now has the help of a Washington 'protocol expert' to help prevent future scandals, and may even find a way to pass down her newfound knowledge.

'I think the president has opened the floodgates for people who aren't necessarily your traditional political types to run for office. So going forward you're going to see a lot more celebrities, more billionaires, people in the tech space, all vying for political office,' she said.

'Maybe I'll create a guidebook for future political spouses. The dos and don'ts in DC.'
