Ivanka Trump is officially joining her dad's White House and taking a government job that will require her to abide by federal ethics rules.

The position will be unpaid.

"I have heard the concerns some have with my advising the president in my personal capacity while voluntarily complying with all ethics rules and I will instead serve as an unpaid employee in the White House office, subject to all of the same rules as other federal employees," she said in a statement.

The statement signaled that the president's daughter bowed to pressure from government ethics groups who had complained that even if she followed the rules voluntarily, she could always withdraw at some point.

Others have expressed general concerns about having a member of the president's family serve in his White House. Congress enacted anti-nepotism laws following the Kennedy administration, but the White House contends they apply only to executive agencies and not the White House itself.

Craig Holman of Public Citizen called it 'good news' that Ivanka was abandoning the voluntary arrangement.

'Ivanka was just getting too imbedded in the White House. She got this coveted office space right in the West Wing,' he told DailyMail.com. 'Once you get out your’e clearly and obviously a government employee. I’m sure even the White House counsel said we can’t even pull this one off.'

Ivanka will have to fill out a financial disclosure form about her business holdings, and the federal Office of Government Ethics will scour it for potential conflicts.

She might have to sell or otherwise remove herself self-named business. Her husband transferred authority over many of his business holdings after negotiating his own ethics agreement.

If she wants to divest of holdings and get a tax break meant to benefit people who comply with ethics guidance to avoid conflicts, she will need to get a sign-off from the OGE that would be made public.

Ivanka has already been serving as a de facto top advisor to her father.

Her surprise announcement came after White House press secretary Sean Spicer defended the arrangement as originally announced, although in a terse fashion.

Her lawyer, Jamie Gorelick said she will file the financial disclosures federal employees must file will be bound by ethics rules.

The White House said it was "pleased that Ivanka Trump has chosen to take this step,' the Associated Press reported.

The action came on the same day liberal firebrand Sen. Elizabeth Warren fired off a blistering letter to the federal Office of Government Ethics about Trump's arrangement.

'Ms. Trump has substantial interests at stake: for example, she has retained ownership of Ivanka Trump Marks LLC, a retail clothing brand. Ms. Trump's increasing, albeit unspecified, White House role, her potential conflicts of interest and her commitment to voluntarily comply with relevant ethics and conflicts of interest laws have resulted in substantial confusion,' Warren wrote.

Ivanka Trump added in her statement: 'Throughout this process I have been working closely and in good faith with the White House counsel and my personal counsel to address the unprecedented nature of my role.'

Her title will be assistant to the president, the New York Times reported.

Gorelick told the paper: 'She will file the financial disclosure forms required of federal employees and be bound by the same ethics rules that she had planned to comply with voluntarily.'

Ivanka’s service as an unpaid employee furthers our commitment to ethics, transparency, and compliance and affords her increased opportunities to lead initiatives driving real policy benefits for the American public that would not have been available to her previously,' the White House told the paper in an email.
