President Trump has retweeted the name of the alleged Ukraine whistleblower on his Twitter feed.

Why it matters: It and a retweet of a Washington Examiner post that also named the purported whistleblower marked the first time Trump has actively promoted the name, despite the fact that some of his allies, including son Donald Trump Jr. have repeatedly done so online.

  • Some conservative media outlets have published the name, but most major outlets have refrained from doing so.
  • A group of Senate Republicans told Politico last month that they did not support naming the whistleblower over fears that doing so might be illegal.
  • Sen. Rand Paul (R-Ky.) called on the media to print the name at a rally in November as President Trump stood alongside him.

What happened: Trump retweeted an official account for his 2020 campaign on Thursday night, which shared a tweet aimed at Mark Zaid, the whistleblower's lawyer.

  • "It's pretty simple. The CIA 'whistleblower' is not a real whistleblower!" the tweet read.
  • It included a link to a Washington Examiner item that had the whistleblower's purported name in the headline.

On Friday night, Trump promoted a tweet by a Trump supporter that included the alleged whistleblower's name and accused him of committing perjury.

By Saturday morning, it appeared that the retweet had been removed when Axios and other news outlets checked. However, a spokesperson for Twitter told Axios an internal systems outage affecting millions of accounts — including Trump's — meant some tweets were not visible to all Twitter users.

What they're saying: The spokesperson clarified that Trump's retweet mentioning the name alleged to be the whistleblower's should be visible to all now.

  • The spokesperson cited Twitter's private information policy that any tweets that include private information about any individual, including the alleged whistleblower, would be in violation of the Twitter Rules. However, names are not considered private information.
  • The spokesperson stressed that the bug was not a security issue nor a cause for concern.
A tweet previously embedded here has been deleted or was tweeted from an account that has been suspended or deleted.

Islamic State claims responsibility for deadly bombing in southern Afghanistan

The Islamic State group claimed responsibility for a massive blast that tore through a crowded Shiite mosque in the southern Afghan city of Kandahar on Friday, killing at least 47 people and injuring dozens more, AP reports.

Why it matters: Friday's attack was the deadliest to strike Afghanistan since the U.S. withdrew its troops from the region and is the second major attack on a Shiite mosque in a week, underscoring the Taliban's growing security threat from other militant groups.

New wave of strikes will test worker power

Thousands of John Deere workers hit the picket line this week after the union smacked down a new worker contract from the farm and equipment maker.

Why it matters: There’s a wave of worker angst spreading across the country. They wield new power that’s come with a historic worker shortage.
