Sirhan Sirhan, the man who shot and killed Robert F. Kennedy 55 years ago in Los Angeles, was denied parole on Wednesday by a panel in California. 

It marks the first time that Sirhan's case has been up for review after a different parole board recommended that he be released in 2021. 

Gov. Gavin Newsom rejected that recommendation in January 2022, arguing that Sirhan still poses a threat to public safety. 

"Mr. Sirhan’s assassination of Senator Kennedy is among the most notorious crimes in American history," Newsom said at the time. "Mr. Sirhan killed Senator Kennedy during a dark season of political assassinations, just nine weeks after Dr. Martin Luther King, Jr.’s murder and four and a half years after the murder of Senator Kennedy’s brother, President John F. Kennedy."

Sirhan, 78, assassinated Robert F. Kennedy at Los Angeles' Ambassador Hotel on June 5, 1968.

RFK, a U.S. senator from New York who was in the midst of a presidential campaign, had just delivered a victory speech in California’s Democratic presidential primary. 

A judge initially sentenced Sirhan to death, but his sentence was commuted to life in 1972 when California briefly outlawed capital punishment. 

Sirhan's attorney filed a writ of habeas corpus last September, arguing that Gov. Newsom's denial of her client's parole was an "abuse of discretion."

A video of Sirhan was played at a news conference after that motion was filed, in which he apologized. 

"To transform this weight into something positive, I have dedicated my life to self-improvement, the mentoring of others in prison on how to live a peaceful life that revolves around nonviolence," Sirhan said last September. "By doing this, I ensure that no other person is victimized by my actions again and hopefully make an impact on others to follow."

Most of Kennedy's surviving children supported Newsom's rejection of Sirhan's release last year, but two of his sons – Douglas Kennedy and Robert F. Kennedy Jr. – have expressed support for his release.

The Senate passed a disapproval resolution Wednesday, formally killing a Biden administration Department of Labor rule that encourages private retirement plan fiduciaries to consider environment, social and governance (ESG) factors when making investment decisions for over 150 million Americans.

The measure, which only required a simple majority to pass, passed the threshold in a 50-46 vote. The House of Representatives passed it Tuesday in a 216-204 vote, with only one Democrat voting for the bill.

"President Biden wants to sacrifice seniors’ retirement savings to fund his political agenda," Sen. Mike Braun of Indiana, who led the bill, told Fox News Digital Tuesday. "Both the Senate and the House have now sent powerful, bipartisan rebukes of the Biden ESG agenda. I’m proud to stand up for Americans’ retirement savings to stop this harmful rule."

Now that both the House and Senate have passed the legislation, it will head to Biden's desk. The White House warned Monday that Biden 'will veto' the bill if it is sent to his desk.

"The President will continue to deliver for America’s workers. If the President were presented with H.J. Res. 30, he would veto it," said the White House in a Statement of Administration Policy defending the use of ESG factors in fiduciary decisions.

"The rule reflects what successful marketplace investors already know – there is an extensive body of evidence that environmental, social, and governance factors can have material impacts on certain markets, industries, and companies," the White House argued while slamming the Trump administration for "chilling" ESG investments.

If Biden does veto it, Congress would have to approve the resolution again in a two-thirds majority vote in both chambers.

Lawmakers have criticized the DOL rule, which went into effect last month, saying it "politicizes" and "jeopardizes" the retirement savings of more than 152 million Americans. 

Last month, Sen. Mike Braun, R-Ind., and Rep. Andy Barr, R-Ky., introduced the bipartisan disapproval resolution, which has the backing of all GOP senators, Democratic Sen. Joe Manchin of West Virginia and more than 100 organizations.

GOP senators discussed the legislation during a press conference Wednesday, saying the Biden administration's move with the ESG rule had "a certain irony," given the administration's rhetoric of working for the American public. 

"And there's a certain irony here, since [the Biden administration] always billed themselves as actually caring about the person who's struggling. People are going to struggle more because of this rule," Sen. Bill Cassidy, R-La., said.

"This weaponizes their retirement accounts against both their future, but also their present," he continued.

Organizations including Heritage Action, Consumers' Research, the State Financial Officers Foundation and others cheered the passage.

Consumers' Research head Will Hild said Wednesday: "Today, Congress sent a clear, bipartisan message to the Biden Administration and Wall Street elites that the American peoples’ voice is being heard and we will no longer allow the administrative state and their billionaire buddies to weaponize our retirements against us."

ESG standards are increasingly used by investors and asset managers to guide their decision-making.

The environmental factors considered often include how a corporation contributes to pollution or climate change. Social criteria examine a company's relationship with employees, ethics, engagement with nonprofits and stake in the community. Governance considers the corporation's leadership, overall ethics and standards, and it includes the makeup of the board of directors and the recipients of their donations.
