Donald Trump behaves like a mobster and has "a low opinion of all black people", according to the US president's former lawyer Michael Cohen.

The allegations come from Cohen's new book, Disloyal: A Memoir, written during his jail term for Trump campaign finance violations, among other crimes.

Cohen claims Mr Trump also made racist comments about Nelson Mandela and Hispanics.

The White House says Cohen is lying.

"Cohen is a disgraced felon and disbarred lawyer, who lied to Congress," press secretary Kayleigh McEnany said in a statement at the weekend. "He has lost all credibility, and it's unsurprising to see his latest attempt to profit off of lies."

In the book, Cohen alleges that Mr Trump is "guilty of the same crimes" that landed him in prison, and calls his former boss "a cheat, a liar, a fraud, a bully, a racist, a predator, a conman". He said he had the mentality of a "mob boss".

Various US news outlets have published quotes from the book, which comes out on Tuesday. Here are some of the key claims.
On black people and Mandela

"As a rule, Trump expressed low opinions of all black folks, from music to culture and politics," Cohen writes in his book.

He claimed Donald Trump said the late South African president and anti-apartheid activist Nelson Mandela was "no leader".

"Tell me one country run by a black person that isn't a shithole. They are all complete [expletive] toilets," Mr Trump once said, according to Cohen.

The words echo similar allegations, from 2018, that Trump referred to African countries as "shithole" nations.

Back then, Mr Trump told reporters: "I am not a racist. I'm the least racist person you have ever interviewed."

Racism accusations have marred his first term and continue to be an issue as the Republican president campaigns for a November re-election against his Democratic rival, Joe Biden.

The Nelson Mandela foundation has responded to the allegations regarding the

former South Africa president affectionately known as Madiba.

"We do not believe that leaders who conduct themselves in the way Mr Trump does are in a position to offer authoritative commentary on the life and work of Madiba," it said in a statement.

"Reflecting on leadership, Madiba once said: 'A good leader can engage in a debate frankly and thoroughly, knowing that at the end he and the other side must be closer, and thus emerge stronger. You don't have that idea when you are arrogant, superficial, and uninformed.' We would recommend these words to Mr Trump for consideration."
On Obama

In the book, Cohen alleges that Mr Trump has "hatred and contempt" for his predecessor, Barack Obama.

"Trump hired a 'Faux-Bama' to participate in a video in which Trump 'ritualistically belittled the first black president and then fired him'," Cohen writes.

US media has since shown an old video, showing Mr Trump reprising his role as the host of The Apprentice television show and firing a man posing as President Obama.

It is believed to have been made for the 2012 Republican convention, when Mitt Romney was nominated as the Republican candidate, but it was never aired.
On Hispanic voters

According to Cohen, Mr Trump once said: "I will never get the Hispanic vote. Like the blacks, they're too stupid to vote for Trump. They're not my people."

His comments on Latin Americans have come under scrutiny throughout his presidency, especially after he repeatedly disparaged Mexicans during his campaign.

In 2019, President Trump told a rally in New Mexico: "Nobody loves Hispanics more."

On evangelicals
Cohen says that after Mr Trump met with evangelical leaders at Trump Tower shortly after he won the election, he turned and said: "Can you believe people believe that [expletive]?"

Mr Trump has heavily courted the evangelical vote and has said he is a deep believer himself. His vice-president, Mike Pence, is a devout evangelical.

On Putin

Donald Trump admired Russian President Vladimir Putin because he was able "to take over an entire nation and run it like it was his personal company - like the Trump Organization, in fact," Cohen writes.

Cohen says Mr Trump was sycophantic to President Putin to ensure access to Russian money if he lost the 2016 election.

However, Cohen also says that Trump's campaign was "far too chaotic and incompetent to actually conspire with the Russian government" when it got into power.
On Stormy Daniels

In 2016, Cohen arranged a hush-money payment to adult-film star Stormy Daniels, who claimed to have had an affair with Mr Trump. The payment, which violated campaign funding rules, was among the crimes that led to Cohen's jail term.

Cohen has long insisted he was acting on the president's orders, but Mr Trump has always denied this.

"It never pays to settle these things, but many, many friends have advised me to pay," Mr Trump said, according to Cohen's book. "If it comes out, I'm not sure how it would play with my supporters. But I bet they'd think it's cool that I slept with a porn star."
Who is Michael Cohen?

Cohen worked closely with Mr Trump for years and was often known as his "fixer", but they fell out and Cohen gave a brutal testimony to Congress last year, prior to Mr Trump's impeachment.

In 2018, Cohen was jailed for tax evasion, false statements and campaign finance violations.

The disbarred lawyer is currently serving what remains of his three-year sentence at his home in New York, having been released from prison amid concerns about the spread of coronavirus.

He was briefly returned to jail, until a federal judge intervened and ruled that the government had made the move in retaliation for him writing his book.

Mr Trump has called Cohen "a rat" and a liar.

Cohen once said he would take a bullet for Donald Trump. He has since said he has received death threats from Trump supporters.
