As Donald Trump's legal woes mount, donors and the Republican party have paid millions in dollars of his legal fees.

His newest legal headache saw him and three of his children hit with a fraud lawsuit, which alleges they lied about the value of the property "by billions".

Financial data shows that he has already spent more than $1m (£890,000) of donations fighting the case in 2022.

Mr Trump has denied any wrongdoing.

The latest lawsuit, announced by New York state Attorney General Letitia James, was the culmination of a long-running civil investigation that began in 2019.

Millions of dollars spent combatting these charges have come from Mr Trump's Save America political action committee (PAC) - which takes donations from Trump supporters across the country - Federal Election Commission (FEC) filings show.

Save America has paid more than $1.12m this year alone to law firms hired to defend Mr Trump in the New York case. As a so-called "Leadership PAC", it can use the money to pay for expenses that cannot be funded by campaign committees, such as some personal travel or some leadership expenses.

The website of Save America's Joint Fundraising Committee - which contributes both to Save America and a second Trump PAC, Make America Great Again - makes no mention of legal bills, saying only that "the future of our Country [sic] is at stake and President Trump is calling on all Patriots to join his fight to Save America".

Of the $1.12m spent, more than $942,000 has gone to the firm of Alina Habba, a New Jersey-based attorney who has doubled as a Trump spokeswoman.

Another lawyer, New York-based Alan Futerfas, received nearly $185,000 in July. Mr Futerfas is representing Mr Trump's children - Don Jr, Ivanka, and Eric - in the New York fraud case.

It is unclear how much of his own money Mr Trump has spent on his legal cases.

One donor told the BBC the idea of funding the lawsuits didn't bother him at all.

"In my opinion, he can do whatever he wants with the money," said Rom Solene, a Republican from Arizona.

"The non-stop nonsense and antics being conducted by the Democrats on a man who no longer holds political office shows the extent to which the Democrats are willing to go to persecute a political opponent. Not to mention, it shows how much the Democrats and other Washington insiders fear Mr Trump."

The fraud investigation is just one of several expensive legal challenges facing the former president, however.

In August alone, Mr Trump spent more than $3.8m on legal fees in the wake of the FBI's search of his Palm Beach estate, Mar-a-Lago, the bulk of which - about $3m - went to a nearby Florida firm.

Smaller amounts went to lawyers involved in his other legal issues, including a Georgia investigation into whether he and his allies tried to illegally overturn the results of the 2020 presidential election.

But there is no indication the former president's method of settling his legal bills violates any statute.

Erin Chlopak, a campaign finance expert at the Campaign Legal Center, a Washington DC-based non-profit, told the BBC that legal expenses often fall into a "grey area", where it is left up to the Electoral Commission to decide if the expense is "personal" or whether it would exist "irrespective of a person's status as a candidate or officeholder, in which case the money can be used".

"That's a real problem in campaign finance law," Ms Chlopak said. "We've seen that not just in the context of legal expenses, but in even more blatant personal uses, like personal travel, dining out at expensive restaurants and staying in hotels."

In Mr Trump's case, Ms Chlopak added, the subject is complicated by the array of legal issues he is currently facing.
