Last week, the President re-Tweeted a link to a Washington Examiner article that claimed to reveal the identity of a U.S. intelligence official who first alerted authorities to the July 25 phone call with Ukraine President Volodymyr Zelenskiy that sparked a Democratic-lead impeachment inquiry.
Trump shared a second report from his personal account that appeared to name the official late Friday, but it was not seen for most of Saturday by the 68 million people that follow it. When it was finally visible Sunday, the original account that posted the link had been disabled.
"Due to an outage with one of our systems, tweets on account profiles were visible to some, but not others," Twitter Support said in a statement posted on its website. "We're still working on fixing this and apologize for any confusion."
Twitter shares were marked 1.24% lower in early trading Monday to change hands at $32.14 each, a move that would trim its year-to-date gain to around 12%.
Earlier this year, Trump accused Twitter using “discriminatory and illegal practices” to muzzle conservative voices and personalities on its mico-blogging website following media reports of "shadow banning" Republican-branded Tweets that limit their potential viewers.
“Twitter ‘SHADOW BANNING’ prominent Republicans. Not good,” Trump Tweeted on July 26. “We will look into this discriminatory and illegal practice at once! Many complaints.”
