US President Donald Trump will sign an executive order targeting social media firms, the White House has said.
It comes after he threatened to shut down social media platforms he accused of stifling conservative voices.
The latest dispute emerged after Twitter added fact-check links to his tweets for the first time.
The order's details have not been shared and it is unclear what regulatory steps the president can take without new laws passed by Congress.
White House officials gave no further information on what is expected in the executive order which is set to be signed on Thursday.
Before leaving Washington for Florida to watch a space launch that was postponed due to bad weather, Mr Trump again accused Twitter and other social media of bias, without offering evidence.
