NEW YORK (AP) — Federal agents raided Rudy Giuliani’s Manhattan home and office Wednesday, seizing computers and cellphones in a major escalation of the Justice Department’s investigation into the business dealings of former President Donald Trump’s personal lawyer.

Giuliani, the 76-year-old former New York City mayor once celebrated for his leadership after 9/11, has been under federal scrutiny for several years over his ties to Ukraine. The dual searches sent the strongest signal yet that he could eventually face federal charges.

Agents searched Giuliani’s Madison Avenue apartment and Park Avenue office, people familiar with the investigation told The Associated Press. The warrants, which required approval from the top levels of the Justice Department, signify that prosecutors believe they have probable cause that Giuliani committed a federal crime — though they do not guarantee that charges will materialize.

A third search warrant was served on a phone belonging to Washington lawyer Victoria Toensing, a former federal prosecutor and close ally of Giuliani and Trump. Her law firm issued a statement saying she was informed that she is not a target of the investigation.

The full scope of the investigation is unclear, but it at least partly involves Giuliani’s dealings in Ukraine, law enforcement officials have told the AP.

The people discussing the searches and Wednesday’s developments could not do so publicly and spoke to the AP on condition of anonymity. News of the search was first reported by The New York Times.

In a statement issued through his lawyer, Giuliani accused federal authorities of a “corrupt double standard,” invoking allegations he’s pushed against prominent Democrats, and said that the Justice Department was “running rough shod over the constitutional rights of anyone involved in, or legally defending, former President Donald J. Trump.”

“Mr. Giuliani respects the law, and he can demonstrate that his conduct as a lawyer and a citizen was absolutely legal and ethical,” the statement said.

Trump told Fox Business on Thursday that Giuliani was “the greatest mayor in the history of New York” and “a great patriot.”

“It’s very, very unfair,” he said of what happened Wednesday. “Rudy loves this country so much, it is so terrible when you see things that are going on in our country with the corruption and the problems and then they go after Rudy Giuliani.”

White House press secretary Jen Psaki said Thursday on CNN that the White House was given no heads’ up on the fact the raid was coming. The Justice Department, she said, “is independent now. They’re gonna make their own decisions, take their own actions. That’s how the president wants it.”

Bernie Kerik, who served as New York City’s police commissioner during the Sept. 11 attacks and is a longtime Giuliani friend, said the former mayor called him as agents were searching his home on Wednesday morning. Kerik, who was pardoned by Trump for felony convictions that put him behind bars for three years, declined to describe his friend’s mood or reaction, but expressed alarm at the raid, saying agents “shouldn’t have been there in the first place.”

“I think it’s extremely concerning,” he said.

Giuliani’s son, Andrew Giuliani, told reporters the raids were “disgusting” and “absolutely absurd.”

A Justice Department spokesperson did not immediately respond to a request for comment. The U.S. Attorney’s office in Manhattan and the FBI’s New York office declined to comment.

The federal probe into Giuliani’s Ukraine dealings stalled last year because of a dispute over investigative tactics as Trump unsuccessfully sought a second term. Giuliani subsequently took on a leading role in disputing the election results on the Republican’s behalf.

Wednesday’s raids came months after Trump left office and lost his ability to pardon allies for federal crimes. The former president himself no longer enjoys the legal protections the Oval Office once provided him — though there is no indication Trump is eyed in this probe.

Trump’s spokesman did not immediately respond to questions about Wednesday’s events.

Many people in Trump’s orbit have been ensnared in previous federal investigations, including special counsel Robert Mueller’s probe of Russian election interference. Some, like former Gen. Michael Flynn, Roger Stone and Paul Manafort, were pardoned. While there were discussions about a pre-emptive pardon for Giuliani, it did not materialize.

Giuliani was central to the then-president’s efforts to dig up dirt against Democratic rival Joe Biden and to press Ukraine for an investigation into Biden and his son, Hunter — who himself now faces a criminal tax probe by the Justice Department.

Giuliani also sought to undermine former U.S. ambassador to Ukraine Marie Yovanovitch, who was pushed out on Trump’s orders, and met several times with a Ukrainian lawmaker who released edited recordings of Biden in an effort to smear him before the election.

Giuliani’s lawyer, Robert Costello, said the warrants involved an allegation that Giuliani failed to register as a foreign agent and that investigative documents mentioned John Solomon, a former columnist and frequent Fox News commentator with close ties to Giuliani, who pushed baseless or unsubstantiated allegations involving Ukraine and Biden during the 2020 election.

Phone records published by House Democrats in 2019 in the wake of Trump’s first impeachment trial showed frequent contacts involving Giuliani, Solomon and Lev Parnas, a Giuliani associate who is under indictment on charges of using foreign money to make illegal campaign contributions.

Contacted Wednesday, Solomon said it was news to him that the Justice Department was interested in any communications he had with Giuliani, though he said it was not entirely surprising given the issues raised in the impeachment trial.

“He was someone that tried to pass information to me. I didn’t use most of it,” Solomon said of Giuliani. “If they want to look at that, there’s not going to be anything surprising in it.”

Everything was sitting “in plain view,” Solomon said. He said he believed his reporting had “stood the test of time” and maintained that he was “unaware of a single factual error” in any of his stories.

Solomon’s former employer, The Hill newspaper, published a review last year of some of his columns and determined they were lacking in context and missing key disclosures. Solomon previously worked for The Associated Press, departing the news organization in 2006.

The federal Foreign Agents Registration Act requires people who lobby on behalf of a foreign government or entity to register with the Justice Department. The once-obscure law, aimed at improving transparency, has received a burst of attention in recent years — particularly during Mueller’s probe, which revealed an array of foreign influence operations in the U.S.

Federal prosecutors in the Manhattan office Giuliani himself once led — springing to prominence in the 1980s with high-profile prosecutions of Mafia figures — had pushed last year for a search warrant for records. Those included some of Giuliani’s communications, but officials in the Trump-era Justice Department would not sign off on the request, according to multiple people who insisted on anonymity to speak about the ongoing investigation with which they were familiar.

Officials in the then-deputy attorney general’s office raised concerns about both the scope of the request, which they thought would contain communications that could be covered by legal privilege between Giuliani and Trump, and the method of obtaining the records, three of the people said.

The issue was widely expected to be revisited by the Justice Department once Attorney General Merrick Garland assumed office, given the need for the department’s upper echelons to sign off on warrants served on lawyers. Garland was confirmed last month, and Deputy Attorney General Lisa Monaco was confirmed to her position and sworn in last week.

DUBAI, United Arab Emirates (AP) — An American warship fired warning shots when vessels of Iran’s paramilitary Revolutionary Guard came too close to a patrol in the Persian Gulf, the U.S. Navy said Wednesday. It was the first such shooting in nearly four years.

The Navy released black-and-white footage of the encounter Monday night in international waters of the northern reaches of the Persian Gulf near Kuwait, Iran, Iraq and Saudi Arabia. In it, lights can be seen in the distance and what appears to be a single gunshot can be heard, with a tracer round racing across the top of the water.

Iran did not immediately acknowledge the incident.

The Navy said the Cyclone-class patrol ship USS Firebolt fired the warning shots after three fast-attack Guard vessels came within 68 yards (62 meters) of it and the U.S. Coast Guard patrol boat USCGC Baranoff.

“The U.S. crews issued multiple warnings via bridge-to-bridge radio and loud-hailer devices, but the (Guard) vessels continued their close range maneuvers,” said Cmdr. Rebecca Rebarich, a spokeswoman for the Mideast-based 5th Fleet. “The crew of Firebolt then fired warning shots, and the (Guard) vessels moved away to a safe distance from the U.S. vessels.”

She called on the Guard to “operate with due regard for the safety of all vessels as required by international law.”

“U.S. naval forces continue to remain vigilant and are trained to act in a professional manner, while our commanding officers retain the inherent right to act in self-defense,” she said.

The last time a Navy vessel fired warning shots in the Persian Gulf in an incident involving Iran was in July 2017, when the USS Thunderbolt, a sister ship to the Firebolt, fired to warn off a Guard vessel. Regulations issued last year give Navy commanders the authority to take “lawful defensive measures” against vessels in the Mideast that come within 100 meters (yards) of their warships.

While 100 meters may seem far to someone standing at a distance, it’s incredibly close for large warships that have difficulty in turning quickly, like aircraft carriers. Even smaller vessels can collide with each other at sea, risking the ships.

The incident Monday marked the second time the Navy accused the Guard of operating in an “unsafe and unprofessional” manner this month alone after tense encounters between the forces had dropped in recent years.

Footage released Tuesday by the Navy showed a ship commanded by the Guard cut in front of the USCGC Monomoy, causing the Coast Guard vessel to come to an abrupt stop with its engine smoking on April 2.

The Guard also did the same with another Coast Guard vessel, the USCGC Wrangell, Rebarich said.

The interaction marked the first “unsafe and unprofessional” incident involving the Iranians since April 15, 2020, Rebarich said. However, Iran had largely stopped such incidents in 2018 and nearly in the entirety of 2019, she said.

In 2017, the Navy recorded 14 instances of what it describes as “unsafe and or unprofessional” interactions with Iranians forces. It recorded 35 in 2016, and 23 in 2015.

The incidents at sea almost always involve the Revolutionary Guard, which reports only to Supreme Leader Ayatollah Ali Khamenei. Typically, they involve Iranian speedboats armed with deck-mounted machine guns and rocket launchers test-firing weapons or shadowing American aircraft carriers passing through the Strait of Hormuz, the narrow mouth of the Persian Gulf through which 20% of all oil passes.

Some analysts believe the incidents are meant in part to squeeze President Hassan Rouhani’s administration after the 2015 nuclear deal. They include a 2016 incident in which Iranian forces captured and held overnight 10 U.S. sailors who strayed into the Islamic Republic’s territorial waters.

The incident comes as Iran negotiates with world powers in Vienna over Tehran and Washington returning to the 2015 nuclear deal. It also follows a series of incidents across the Mideast attributed to a shadow war between Iran and Israel, which includes attacks on regional shipping and sabotage at Iran’s Natanz nuclear facility.
