President Donald Trump’s son-in-law and senior adviser Jared Kushner is reportedly furious over persistent rumors that New Jersey Governor Chris Christie is angling for a job in the White House.

Kushner’s displeasure at the prospect of Christie working alongside him at 1600 Pennsylvania Avenue was reported by anonymous sources who spoke to Politico.

The news site wrote a lengthy article detailing the on-the-job hardships that Trump has experienced in his first month as president.

Trump is reported to be surprised at the difficulties in implementing the changes he has sought in running a large federal bureaucracy.

The president is also reportedly at the helm of a tired, demoralized staff whose members are largely unclear about their roles and are constantly looking over their shoulder in fear of upsetting the boss.

Kushner is described in the article as a man who wields power but whose area of responsibility in the White House is largely undefined – making it difficult for colleagues to gauge where they stand with him.

After Trump won the election on November 9, it was long expected that Christie would assume a senior role in his administration.

Christie was offered a number of positions within the new Trump administration – though not the gig he wanted, attorney general – and so he turned them all down.

The New Jersey governor was reportedly offered the homeland security secretary’s position, veterans affairs secretary, the ambassadorship to Italy, or a role as a White House adviser.

Christie rejected those offers because none of them included the job he really wanted – attorney general, according to NJ.com.

Trump would eventually name Jeff Sessions, the Alabama senator, to the attorney general’s position.

The governor was also said to be interested in the chairmanship of the Republican National Committee, but that position was also never offered.

Because of Trump's Atlantic City casino connections, the president-elect and the New Jersey governor have known each other for 15 years.

Christie was one of the first major Republican Party figures to back Trump in the primary, as he endorsed the billionaire shortly after giving up on his own White House dreams.

Trump paid back Christie the favor by naming him the head of the Trump transition team.

However, Christie reportedly was on the outs with members of Trump's team.

He was replaced by Vice President-elect Mike Pence as head of the transition and made a vice-chair instead.

Christie's departure was thought to be because he was politically vulnerable due to the fallout from the Bridgegate scandal.

Two of his aides were convicted recently of engineering the closure of a lane on the George Washington Bridge as political payback against the mayor of Fort Lee, New Jersey - a Democrat who declined to endorse Christie for governor.

Christie has denied any wrongdoing, though the affair is believed to have destroyed his political future, according to The Washington Post.

There was also speculation that Kushner was the one who pushed Christie out - and the motive was personal.

When Christie was a US attorney in the early part of last decade, one of his biggest legal triumphs was the imprisonment of Jared Kushner’s father, Charles Kushner.

Charles Kushner, the billionaire real estate developer, went to prison after he pleaded guilty to tax evasion and illegal campaign contributions to New Jersey’s Democratic governor, Jim McGreevey.

The Kushner case generated headlines and catapulted Christie to political stardom.

Jared Kushner was quoted as saying that his father’s arrest and imprisonment were ‘unjust’ and that the whole affair dissuaded him from becoming a lawyer.

‘My dad's arrest made me realize I didn't want to be a prosecutor anymore,’ Jared Kushner is quoted as saying by CNN.

‘The law is so nuanced. If you're convicting murderers, it's one thing. It's often fairly clear.

‘When you get into things like white-collar crime, there are often a lot of nuances.

‘Seeing my father's situation, I felt what happened was obviously unjust in terms of the way they pursued him.

‘I just never wanted to be on the other side of that and cause pain to the families I was doing that to, whether right or wrong.

‘The moral weight of that was probably a bit more than I could carry.’

In an interview with Forbes, Jared Kushner denied that he held a grudge against Christie.

‘Six months ago Governor Christie and I decided this election was much bigger than any differences we may have had in the past, and we worked very well together,’ Jared Kushner told Forbes.

‘The media has speculated on a lot of different things, and since I don't talk to the press, they go as they go, but I was not behind pushing out him or his people.’

Charles Kushner received a two-year sentence in a federal penitentiary.

He served 14 months at Federal Prison Camp in Alabama before he was sent to a halfway house in Newark, New Jersey, to complete his sentence.

He was released from prison on August 25, 2006.

Christie has said that he will complete his second and final term as New Jersey governor.

The next gubernatorial election in the Garden State is scheduled for November 7, 2017.
