Ivanka Trump

But she will not have an official title or salary when she works in the West Wing - the hub of US executive power.

The official also confirmed media reports that the 35-year-old would have access to classified information.

Her role will be to serve as Donald Trump's "eyes and ears" while providing broad-ranging advice, her attorney was quoted as saying by Politico.

Ivanka, who has her own fashion brand, will be joining her husband Jared Kushner, who is a senior adviser to the president.

Abigail Klem, president of the first daughter's brand of companies, confirmed to The New York Times Monday that Ivanka Trump Fine Jewelry is being discontinued. Instead, the company will focus its efforts on costume jewelry, with a more accessible price point.

The Office of Government Ethics (OGE) found reason to believe Ms Conway had violated ethics rules, five days after she urged people to buy the president's daughter's range on Fox News.

Her comments prompted complaints from both Democrats and Republicans.

They have now been backed by the OGE, which is an independent body.

In a letter on Tuesday, it advises the White House to investigate and possibly discipline Ms Conway.

@POTUS, the official Twitter account for the president, had so far been reserved for government issues.

The Trump tweet blasted Nordstrom for treating his daughter Ivanka "so unfairly" by discontinuing her fashion line.

Nordstrom announced last week that it would no longer carry Ivanka Trump's line of clothing and accessories.

The president went on Twitter to defend his daughter -- who is also a close White House adviser.

"Your father is ruining the country," the man shouted as the aircraft prepared for departure from JFK airport in New York, a passenger told TMZ.com.

Witnesses said Ms Trump ignored the man and distracted her children with toys.

JetBlue airlines said in a statement that "the decision to remove a customer from a flight is not taken lightly".

Quincy Bulin, a copy intern for Ms Trump's website who said this was her "third unpaid summer in New York", banded together with other interns at Ivanka Trump HQ to offer tips on how to get by.

The article was actually written last month, but had a re-birth when it was tweeted again from Ms Trump's Twitter account with the hashtag #nomoneynoproblems.

Unsurprisingly, the fact that Ms Trump — the daughter of billionaire presidential nominee Donald Trump — is offering advice on how to make ends meet has ignited outrage online.

That seemed to be the question on everybody's mind once Donald Trumpbegan his campaign for presidency, and it was only heightened after hearing the entrepreneur and daughter of the Republican nominee speak on his behalf at the RNC in Cleveland.
