President Donald Trump suggested he would be willing to arrest California Gov. Gavin Newsom if his administration obstructs ICE operations amid riots in Los Angeles on Monday.

Trump made the statement in a brief exchange with reporters after disembarking from Marine One outside the White House. Fox News White House correspondent Peter Doocy asked Trump whether he though Border Czar Tom Homan should take up Newsom on his dare to come arrest him.

"He's daring Tom Homan to come and arrest him. Should he do it?" Doocy asked.

"I would do it I were Tom," Trump responded. "I think it's great. Gavin likes the publicity. But I do think it would be a great thing.  He's done a terrible job. I like Gavin Newsom. He's a nice guy, but he's grossly incompetent. Everybody knows."

Trump went on to state his belief that many of the rioters and protesters in Los Angeles are professional agitators rather than real protesters.

"The people that are causing the problem are professional agitators. They're insurrectionists. They're bad people. They should be in jail," Trump said.

Newsom swiftly responded to Trump's comments in a post on social media.

"The President of the United States just called for the arrest of a sitting Governor," Newsom wrote. "This is a day I hoped I would never see in America. I don’t care if you’re a Democrat or a Republican this is a line we cannot cross as a nation — this is an unmistakable step toward authoritarianism."

Homan told "Fox & Friends" earlier on Monday that he had told an NBC reporter that "no one's above the law," but there was no discussion about arresting Newsom at that time.

"What we discussed was for those protesters that crossed the line… you can protest, you get your First Amendment rights… But when you cross that line, you put hands on an ICE officer, or you destroy property, or I'd say that you impede law enforcement, or you're knowingly harboring and concealing an illegal alien… that's a crime, and the Trump administration is not going to tolerate it," he said.

"Then the reporter asked me, well, could Governor Newsom or Mayor Bass be arrested? I said, 'Well, no one's above the law. If they cross the line and commit a crime, absolutely they can,' so there was no discussion about arresting Newsom."

Homan lambasted the blue state's response to riots against the Trump administration's immigration raids that rocked Los Angeles over the weekend, with some protesters throwing projectiles at law enforcement and torching American flags and cars.

Trump deployed 2,000 National Guard troops to the city in an effort to quell some of the unrest, much to the dismay of Democratic officials.

Iran’s refusal to play ball with the United Nation's nuclear watchdog, which is charged with monitoring all nations' nuclear programs, has meant the body cannot verify whether Tehran’s program is "entirely peaceful" despite the regime's claims.

Director General of the International Atomic Energy Agency (IAEA), Rafael Grossi, on Monday issued a warning statement that the agency has not only long been barred access to old and new nuclear sites, but that Iran has scrubbed locations in an apparent move to cover up its activities.

In 2020, the IAEA found man-made particles of enriched uranium at three sites, including Varamin, Marivan and Turquzabad. The locations were previously utilized in Iran’s nuclear program and gave the agency credence to believe Tehran had once again turned to deadly nuclear ambitions.

"Since then, we have been seeking explanations and clarifications from Iran for the presence of these uranium particles, including through a number of high-level meetings and consultations in which I have been personally involved," Grossi said. "Unfortunately, Iran has repeatedly either not answered, or not provided technically credible answers to, the Agency’s questions. 

"It has also sought to sanitize the locations, which has impeded Agency verification activities," he added. 

Grossi, who confirmed during an April trip to Washington, D.C. that the IAEA has not been involved in nuclear negotiations between the U.S. and Iran, said on Monday that he has been working "closely and intensively" with both parties in "support of their bilateral negotiation[s]."

The warning comes after the IAEA in a report late last month, also confirmed that Iran had drastically increased its stockpile of near-weapons-grade enriched uranium by nearly 35% in three months.

In February, the IAEA assessed that Tehran possessed 274.8 kilograms (605.8 pounds) worth of uranium enriched to 60%, but on May 17th it found Iran now has some 408.6 kilograms (900.8 pounds) – meaning the regime is just a technical step away from being able to make up to 10 nuclear warheads. 

Last week, Iranian supreme leader Ayatollah Ali Khamenei came out in strong opposition to a U.S. proposal submitted to Tehran to end its nuclear program, though it remains unclear what details were included in the document, including on enrichment capabilities, and on Sunday, Iranian parliamentary speaker Mohammad Bagher Ghalibaf claimed the proposal didn’t include any sanction relief.

The White House has remained tight-lipped about what was included in the document, though according to some reporting, President Donald Trump gave Iran until June 11 to reach a deal with the U.S., though Fox News Digital could not independently verify these claims. 

On Monday, Iranian Foreign Ministry spokesperson Esmaeil Baghaei confirmed that "The U.S. proposal is not acceptable to us. It was not the result of previous rounds of negotiations."

"We will present our own proposal to the other side via Oman after it is finalized. This proposal is reasonable, logical, and balanced," Baghaei reportedly said.

Some reporting has also suggested Iran might submit their proposal as soon as June 10, though the Iranian UN mission in the U.S. would not comment on or confirm these claims.
