Two top aides to ousted Fox News chief Roger Ailes have been subpoenaed and met with federal prosecutors in New York, as a federal investigation into Fox News' handling of sexual abuse settlements expands into a look at alleged intimidation tactics against perceived threats, The Wall Street Journal and The New York Times reported Thursday night. Both men — former CFO Mark Kranz, who resigned last year, and former public relations chief Brian Lewis, fired in 2013 — have reportedly been granted immunity from prosecution. The investigation is being conducted by two prosecutors in the securities fraud unit at the U.S. Attorney's office in Manhattan and criminal investigators from the U.S. Postal Inspection Service, a federal law enforcement agency that helps tackle white-collar crime.

The federal investigators have also interviewed at least two women who have accused Ailes of sexual harassment, on-air contributor Julie Roginsky and former director of corporate events Lauri Lunh, The Wall Street Journal reports. Along with investigating whether the settlements paid to accusers violated securities laws, the feds are looking into Ailes' use of a private investigator, Bo Dietl, to dig into the background of women accusing Ailes and ousted Fox News star Bill O'Reilly of sexual harassment. Ailes and O'Reilly deny the harassment accusations.

Separately, a former Fox News Radio reporter, Jessica Golloher, sued Fox News on Thursday for gender discrimination, saying that she was told her position was being eliminated less than 24 hours after reporting the years of alleged discrimination to human resources, as encouraged last month. The suit says Golloher was told her duties were being reassigned to freelancers, but that's "entirely pretextual, as it is apparent that Fox will replace Ms. Golloher." Fox News says her suit is "without merit."

Finally, one of O'Reilly's accusers, Wendy Walsh, and lawyer Lisa Bloom are meeting in London on Monday with British regulators at the Office of Communications (Ofcom), which is considering the move by 21st Century Fox — the parent company of Fox News, controlled by Rupert Murdoch — to purchase the rest of satellite TV broadcaster Sky. Buying Sky is a long-time goal of Murdoch, and Bloom wrote Ofcom last month, saying "the similarities between the current harassment scandal and the [2011] phone-hacking scandal reveal the company's approach to business and management — a lack of oversight, intervention, and decency."

The Senate would probably want to hear from a firsthand witness in President Trump's impeachment trial. But Sen. Josh Hawley (R-Mo.) isn't sure where you'd find one.

Despite a Sunday report indicating former National Security Adviser John Bolton will say in his book he spoke directly to President Trump about Ukraine, a number of GOP senators still don't want to hear from him in Trump's impeachment trial. Hawley is among those lawmakers, giving new reasoning to his anti-Bolton argument Monday by questioning whether Bolton even was a firsthand witness to Trump's alleged crimes.

Bolton's book reportedly describes how Trump talked to his former adviser about withholding security assistance from Ukraine until it agreed to investigate former Vice President Joe Biden. And with Republicans largely complaining impeachment witnesses testified to the House based on "hearsay," one would think they'd like to hear from someone who was actually in, as Bolton's book title so aptly puts it, "the room where it happened."

Details are still emerging about the circumstances surrounding the helicopter that killed Los Angeles Lakers legend Kobe Bryant, his 13-year-old daughter Gianna, and seven others including the pilot, but the flight was reportedly granted special approval to fly in challenging weather conditions.

Fog was thick Sunday morning in the Los Angeles area when the helicopter took off and made its way toward Gianna Bryant's youth basketball tournament, but air traffic control at Burbank airport gave the pilot Special Visual Flight Rules clearance, allowing the aircraft to enter Burbank's airspace.

A Federal Aviation Administration official said air traffic control's approval would not have extended to Calabasas, where the helicopter crashed. By that point, the official said, it would have been up to the pilot to determine if conditions were appropriate to continue or transition to instrument flight rules.

Witnesses near the site of the crash described conditions as so foggy that people had trouble driving, per The New York Times. "I couldn't see anything, not even a silhouette," said Scott Daehlin who heard the sound of the helicopter flying low before making impact with a nearby hillside. "My first thought was what in the world is a helicopter doing out here in this fog?" Read more at The New York Times. Tim O'Donnell

Immigrants may now face visa and citizenship restrictions based on their past or hypothetical future use of public benefits.

In a 5-4 decision Monday, the Supreme Court allowed the Trump administration's public charge rule to take effect nationwide. The rule would restrict immigrants who are considered or could later be considered a "public charge" from gaining legal status, and comes despite multiple prior courts striking down the rule.

The Monday decision came along ideological lines, with the court's four liberal justices dissenting from the majority opinion. U.S. District Judge George Daniels previously struck down the rule, mirroring critics who've called it a "wealth test" for immigrants by saying the rule is "repugnant to the American dream." Daniels had also placed an injunction on the rule's implementation due to a likely appeal to the Supreme Court, and the higher court lifted that injunction Monday.

The theory of a public charge rule has existed for decades, but wasn't codified until the Trump administration drew up this rule in 2017. The rule targets people attempting to legally immigrate into the U.S. by assessing if they have used public benefits such as food stamps in the past, or if they might use them after gaining legal status. If the government determines a person is or could become a "public charge," they can block a person from getting a visa, green card, citizenship, and other forms of legal status. Kathryn Krawczyk

More than two decades after his investigation of former President Bill Clinton, Ken Starr while defending President Trump on Monday asked how it is we came to live in the "age of impeachment."

The former independent counsel spoke as part of Trump's legal defense team during the Senate's impeachment trial, making the argument that presidential impeachments are being invoked too often in recent years.

"The Senate is being called to sit as the high court of impeachment all too frequently," Starr said. "Indeed, we're living in what I think can be aptly be described as the age of impeachment. ... How did we get here?"

Starr went on to decry the fact that impeachment has become not a "once in a century phenomenon" but rather a "weapon to be wielded against one's political opponent." He added the Senate should return to a time when "impeachment was truly a measure of last resort."

Given Starr's role in the last presidential impeachment, CNN's John Avlon asked "who thought that Ken Starr was the best choice to make the case for bipartisan process and against impeachment," while MSNBC's Garrett Haake observed, "Ken Starr, arguing against overly-political, thinly-predicated impeachment is enough to make a certain generation of Democrats' heads explode."

Ever since leaks from former National Security Adviser John Bolton's forthcoming book made their way to the public, the odds of the Senate calling him as a witness to take the stand in President Trump's impeachment trial appear to have gone up. Speculation about other witnesses has also entered the fold. One of those potential witnesses is acting White House Chief of Staff Mick Mulvaney, who famously admitted to Trump's Ukraine quid pro quo during a press conference last year.

But through his lawyer, Mulvaney denied knowing anything about the revelations in Bolton's books or ever having a conversation with Trump about freezing Ukrainian military aid in exchange for announcing investigations into Trump's domestic political opponents.

At first glance, it seems like Mulvaney and his counsel are taking a proactive approach should the Senate issue a subpoena, as well as launching an effort to discredit Bolton. But CNN's Jake Tapper pointed out that Bolton may not have alerted Mulvaney to his concerns about the Trump administration's Ukraine policy because he reportedly thought Mulvaney played a central role in its formation.

Federal prosecutors want to talk to Prince Andrew as part of their Jeffrey Epstein investigation, but they're apparently not having much luck.

Geoffrey Berman, U.S. attorney for the Southern District of New York, said Monday that federal prosecutors and the FBI are seeking an interview with Prince Andrew as they continue to investigate Epstein's co-conspirators. According to Berman, though, Andrew has provided "zero cooperation," The New York Times reports.

Prince Andrew has faced scrutiny over his ties to the convicted sex offender, who was found dead in his jail cell last year while awaiting trial on sex trafficking charges. Virginia Roberts Giuffre has claimed Epstein forced her to have sex with Prince Andrew when she was 17, which he has denied.

After a widely-panned interview last year in which Prince Andrew said Epstein "conducted himself in a manner unbecoming," he announced he would "step back from public duties for the foreseeable future," citing the fact that "my former association with Jeffrey Epstein has become a major disruption." At the time, he said that "of course, I am willing to help any appropriate law enforcement agency with their investigations, if required."

As prosecutors seek Prince Andrew's cooperation, Berman emphasized Monday, per The Associated Press, "Jeffrey Epstein couldn't have done what he did without the assistance of others, and I can assure you that the investigation is moving forward." Brendan Morrow
