San Francisco, May 28 (TIWN) Micro-blogging site Twitter has tagged two tweets of US President Donald Trump on mail-in voting with a fact-checking warning label.

The US president has made similar threats before, but so far any attempt to regulate large technology companies has stumbled because of a lack of cross-party support.  The move comes six months ahead of the US presidential election and marks the first time Twitter has sought to check the president’s use of the platform to broadcast controversial statements. The move drew an immediate pushback from Mr Trump and his re-election campaign.
