Donald Trump has suggested that sending him to prison could prove a "breaking point" for his supporters -- a warning that will fuel concerns of political violence around the US presidential election on November 5.

In an interview aired Sunday on Fox News, the former president and current Republican White House hopeful acknowledged the possibility of jail time or house arrest following his historic criminal conviction in a hush money trial.

"I'm ok with it," Trump said, but added he was "not sure the public would stand for it."

"I think it would be tough for the public to take. You know at a certain point there's a breaking point," he said.

The warning will resonate in a country already concerned about the prospect of civil unrest and political harassment in the run-up to the November election.

Trump will now be running as a felon, and he has repeatedly refused to commit to accepting the result should he lose to President Joe Biden.

A New York jury on Thursday convicted Trump on all 34 felony charges of falsifying business records late in the 2016 presidential campaign to cover up a sex scandal involving adult film star Stormy Daniels.

It was the first criminal conviction of a former president in US history, and sentencing has been set for July 11 -- days before the Republican National Convention that will formally anoint Trump as the party's presidential nominee.

"They're turning Donald Trump into a martyr," Trump's son Eric told Fox News.

Although each charge carries a possible four-year jail term, experts say it is extremely unlikely the judge will hand down a custodial sentence.

Nevertheless Trump himself joined the stark call by fellow Republicans, including House Speaker Mike Johnson, for the US Supreme Court to somehow intervene in favor of the ex-president.

A "Local Judge, appointed by the Democrats, who is HIGHLY CONFLICTED, will make a decision which will determine the future of our Nation?" Trump said on his Truth Social media platform. "The United States Supreme Court MUST DECIDE!"

Trump has said his legal team will appeal the hush money verdict. Since it is a New York case, it would have to go through state appellate courts before it reaches the US Supreme Court.

Trump faces three other criminal trials, including one related to efforts to overturn the results of the 2020 presidential election he lost to Biden.

The 77-year-old's supporters stormed the US Capitol on January 6, 2021 after he delivered a fiery speech urging the crowd to "fight like hell."

Democratic congressman Adam Schiff, a member of the House of Representatives committee that investigated the Capitol attack, said Trump's strategy was clear.

"This is essentially his threat that, if he gets jail time, that he's going to encourage his supporters to rise up," Schiff said on CNN's "State of the Union" program.

"And we saw the very deadly results of that on January 6."

- 'Vindicated' -

Breaking her silence following Trump's conviction, Stormy Daniels told British media the ex-president should be incarcerated.

The former adult film actor helped bring Trump down in court with her gripping testimony, which included graphic descriptions of what she says was a casual sexual encounter in 2006.

Trump has continued to deny the sexual encounter, which prosecutors at his trial said occurred shortly after his wife Melania had given birth.

In his Fox interview, Trump said the trial had taken a toll on his wife, who was notably absent from the courtroom, unlike other close family members.

"She's fine, but I think it's very hard for her," Trump said. "She has to read all this crap."

Trump denies saying 'lock her up'

Donald Trump falsely claimed Sunday that he did not call for former election rival Hillary Clinton to be jailed, telling Fox News: "I didn't say 'lock her up'."

Trump, who is facing sentencing -- and possible prison time -- after becoming the first US president to be convicted of a felony, repeatedly demanded Clinton be put behind bars during their 2016 election battle.

The "lock her up" chant was notorious at his rallies during the campaign and for years after, and he stated that he agreed with it or called for her jailing on multiple occasions.

During the interview aired Sunday, Fox host Will Cain asked the 77-year-old about the call, which refers to Clinton's use of a private email server while she was secretary of state.

"You famously said, regarding Hillary Clinton, 'Lock her up.' You declined to do that as president," Cain said.

"I beat her," Trump replied. "It's easier when you win. And they always said 'lock her up,' and I felt -- and I could have done it, but I felt it would have been a terrible thing. And then this happened to me. And so I may feel differently about it."

He went on to deny joining in the chant.

"I didn't say 'lock her up,' but the people said lock her up, lock her up," Trump said.

"Then, we won. And I say -- and I said pretty openly, I said, all right, come on, just relax, let's go, we've got to make our country great."

US media swiftly fact-checked the claim, and some social media users posted supercuts of the Republican agreeing with the chant or explicitly calling for Clinton to be jailed.

Clinton, the wife of former president Bill Clinton, was investigated over her use of a private email server but no charges were filed.

Trump was convicted last week of 34 counts of falsifying business records to cover up hush money payments to an adult film star ahead of the 2016 election.

His sentencing date is July 11. In the Fox News interview on Sunday he also acknowledged the possibility that he could be handed jail time or a prison sentence, warning that while he was "ok with it" such a move could prove a "breaking point" for his supporters.

The warning has resonated in a country already concerned about the prospect of political violence in the increasingly heated run-up to the November 5 presidential election.
