Bill Clinton's half brother Roger, nicknamed 'headache' by the Secret Service during Clinton's presidency, has tried to keep a low-profile as his sister-in-law Hillary positions her family to move back into the White House.

But now it is revealed today that he used his brother-in-law's name to win a $100,000 consulting contract with a company looking to build houses in Haiti.

And it is also disclosed that he is living in a home that was partly - if not fully - paid for by Bill through a limited liability company registered to the Clintons' family home in Chappaqua, New York.

The use of such a device was described as having the potential to 'raise eyebrows' with the IRS. It was never disclosed by Hillary during her time in office that address was linked to the limited liability company.

Roger Clinton's antics in the '90s were a constant source of embarrassment for the first family, culminating in a 2001 congressional investigation over his attempts to 'cash in' on his connections to the White House.

The wannabee rock star, who went to prison in 1985 for cocaine abuse and for a time played in a band called Politics, was found to have engaged in 'serious and reckless misconduct' the review panel.

He has resurfaced just as Hillary tries to put a troubled start to her campaign for presidency behind her with her first television interview of her candidacy.

Roger currently lives in Los Angeles, California, on an $857,000 property he told the New York Times that he co-owns '50-50' with Bill, whom he calls 'Big Brother.'Roger

'I put 50 percent of the money into it,' Roger, 58, told the publication during an interview, conducted at his home.

As the Times points out, if true, that could prove legally problematic for the younger Clinton because he owed the California and federal governments more than $100,000 in unpaid taxes and the IRS was to acquire any 'property now owned or later acquired' by him.

The house was purchased in 2009. It says the liens were removed in 2010 and 2011. If Roger did help purchase the property, that would constitute tax evasion.

'If I was still working at the I.R.S. and someone came to me with this, it would raise eyebrows and trigger me to dig further to find out what exactly was going on,' David Holtz, a former IRS litigator who lives in Los Angeles, told the Times.

A source familiar with the situation told the publication, however, that Bill Clinton purchased the property through a LLC so that his brother and his teenage nephew would have a place to live but he would not be personally responsible for the home as he would not be living in it.

It's possible that Roger Clinton could have contributed to the purchase of the home but it is not clear how he would have done that given that the Times found no sustained record of income for him since, other than the $5,000-a-month deal with Living Modular, the company seeking to build low-cost homes in Haiti.

That deal itself raised questions as the man behind it suggested Roger Clinton promised to deliver a contract with his brother's foundation.

'I paid Roger $100,000,' businessman Wayne Coleman said. 'Basically, he promised to get us a contract through the Clinton Foundation for a project over there. What he was really trying to do was sell the influence of his brother.'

Roger was successful in getting the companies' model included in an expo that Bill Clinton attended on behalf of The Clinton Foundation.

His brother did not choose to invest in the company's product, though – a decision Roger talked up to 'lawyers and advisers' rather than his brother, whom he said 'loved' the effort.

'You had all this government grant money, and all this money Bill was raising from around the world for reconstruction,' he told the Times. 'But we just couldn’t make it happen. It’s like, come on, man, can’t you just throw me a bone?'

Roger Clinton said that 'seven out of 10 times' being related to Bill and Hillary worked against him when trying to win major contracts because it would be interpreted as nepotism.

'I don’t have a choice of being first brother,' Clinton lamented. 'It’s not like I’ve been given the option of doing it and I could turn it down. There are times when it’s hard.'

Sources who spoke to the Times said that Roger and his family have long benefited from his big brother's monetary success in other ways, though.

Bill Clinton reportedly paid for Roger's grown-up daughter to attend cosmetology school.

And, after leaving the White House, when he worked at investment firm Yucaipa, Bill Clinton is said by a former employee to have regularly written his brother checks.

On another occasion, Roger's lawyer floated paying out a settlement over a domestic dispute involving two women on Clinton's property with Bill's money.

Bill and Hillary Clinton's siblings have been accused on numerous occasions of trying to profit off of their relationships with the political power couple, and usually inappropriately.

Hillary's older brother Hugh pocketed $400,000 from a Democratic Party donor – that he was later forced to give back – after he successfully lobbied Bill to commute the federal prison sentence of the donor's drug-dealing son.

Her younger brother, Tony Rodham, also convinced Bill to grant a presidential pardon that he said he wasn't paid to lobby for but a congressional investigation later found that he was.

He's continued to ride the coattails of his brother-in-law, using the Clinton Foundation as a means to an ends of his own contracts in Haiti.
