CNN imageEllliott Management, a top activist shareholder firm, disclosed Monday that it has taken a $3.2 billion stake in AT&T.
The activist investor also called for AT&T to buy back more stock, increase its dividend and pay down debt.
Trump said in two tweets that the Elliott stake was "great news," adding that perhaps Elliott "will now put a stop to all of the Fake News emanating from its non-credible 'anchors.'"
It's also worth noting that Elliott's stake, while significant, makes it just the sixth-largest institutional owner in AT&T, at a little more than 1%.
Elliott Management is run by billionaire investor Paul Singer, who famously battled Argentina over its mutlibillion dollar debt defaults.
