Two White House officials are preparing to leave the Trump administration, reports say. However, she did not address the accuracy of the report.
"Does [CBS News] know something I don't about my plans and my future?" she posted.
Sanders plans to leave at the end of the year, according to CBS. Several high-profile aides, including John F. Kelly, the president's chief of staff, and Joe Hagin, a deputy of Mr. Kelly's, are said to be thinking about how much longer they can stay.
CBS News wrote that neither "Sanders nor Shah immediately responded to repeated requests for comment". She replaced Sean Spicer.
But reports from the USA now say that White House Press Secretary Sarah Huckabee Sanders is set to leave the White House.
