The Supreme Court has agreed to take up rule on whether Donald Trump is immune from prosecution in the Justice Department’s election interference case. The decision means a high-profile trial will be further delayed — if it even takes place at all. The court will begin hearing oral arguments on April 22. The Justice Department indicted Trump last August over his efforts to overturn the results of the 2020 election. The former president has spent recent months trying to get the case thrown out, arguing he is immune…

Les Moonves, the former president and CEO of CBS, tried to influence now-retired LAPD Captain Cory Palka amid a sexual assault investigation against the executive, new documents from the Los Angeles City Ethics Commission found. The legal documents, made public on Friday and obtained by NBC4, revealed that Moonves agreed to pay an $11,250 fine on Feb. 5 for violating the city’s ethics code by “inducing” a city official to misuse his position for Moonves’ benefit. The Ethics Commission found that…

A group of 20 tech companies announced on Friday they have agreed to work together to prevent deceptive artificial-intelligence content from interfering with elections across the globe this year. The rapid growth of generative artificial intelligence (AI), which can create text, images and video in seconds in response to prompts, has heightened fears that the new technology could be used to sway major elections this year, as more than half of the world's population is set to head to the polls.Elevate Your Tech Prowess…

Donald Trump secured his second victory in the Republican 2024 presidential primaries on Tuesday with a comfortable win in New Hampshire. Despite the win, the former president and his allies are still whining, claiming the race was marred by fraud perpetrated by … undeclared voters?  Trump’s sole remaining opponent, former South Carolina Governor Nikki Haley, managed to close the gap between herself and Trump, making significant strides among independent and undeclared voters participating in the primary, a…

WASHINGTON, D.C. – Americans in the nation's capital told Fox News their biggest concerns about artificial intelligence, with some saying they were afraid the rapidly advancing tech could lead to voter manipulation during the 2024 election cycle or eliminate jobs."When things like that have too much control … the power to swing is too far," Cori, of Washington, D.C., told Fox News. "I do think that its gotten wildly out of control."WATCH MORE FOX NEWS DIGITAL ORIGINALS HEREAI's rapidly growing tech has consistently…

It’s been a long time since virtually anyone in the elite of right-wing media, the national Republican Party, or conservative grassroots leadership has thought Ron DeSantis wasn’t going to be a loser. But Iowa was the 2024 state that was supposed to be his biggest gimme. On Monday night, even that fantasy came crashing down. Trump dominated Iowa, so much so that the Associated Press called the race barely 30 minutes after caucuses began. Entrance polls showed Trump  30 points ahead of DeSantis and Nikki Haley, who…
