(CNN) -- FoxNews.com alerted the Secret Service on Monday about the apparent hacking of its Twitter feed for political news, after the feed was used to falsely report that President Obama was killed.
Jeff Misenti, Fox News Digital's vice president and general manager, said in a statement that the website has also requested "a detailed investigation from Twitter about how this occurred, and measures to prevent future unauthorized access into FoxNews.com accounts."
The site took down the false tweets after several were there for hours.
One of the tweets from @FoxNewsPolitics said Obama was "shot twice at a Ross' restaurant in Iowa while campaigning. RIP Obama, best regards to the Obama family."
"We wish @joebiden the best of luck as our new President of the United States. In such a time of madness, there's light at the end of tunnel," the last in the series of tweets said later.
An article on FoxNews.com confirmed the hack.
"Hackers sent out several malicious and false tweets claiming that President Obama had been assassinated," it said. "Those reports are incorrect, of course, and the president is spending the July 4 holiday with his family.
"The hacking is being investigated, and FoxNews.com regrets any distress the false tweets may have created." (Continues here)
